Malloy and Reed investigate an extortion racket against a group of Jewish Holocaust survivors, with the owner of a dry cleaners willing to testify but others not out of fear of retribution. The officers return to handle the owner's panel truck being set ablaze and later the owner is physically assaulted. Malloy and Reed capture both suspects. Other incidents involved a robbery at a bar (the perps escaped initially, but are later captured after a shootout), and a drunk man owed back pay by a dockmaster threatens to dump his boat onto dry land from a crane unless he's paid.

Police "buff" Jennings Thornton, a thorn in the side for Malloy and Reed, intervenes in a drunk driving case, runs down a shooter after a robbery (and nearly getting Reed killed), and is finally arrested himself for falsely arresting two teenage boys for stealing mag wheels that were actually legally bought. Another case involves a woman who stole an expensive ring from a store, leaving a cheap one in return; the suspect is later arrested during a parking lot dispute and the ring is found on her during a search

Malloy and Reed investigate a robbery in a store run by a group of "grandmothers", who sell small homemade items, then later return the money. The suspect later robs an antique shop but is captured when he returns to the first store to attempt another robbery, and the officers purchase some items from the "grandmothers". Other incidents include a high-speed chase of three robbery suspects, who are captured with the help of Sgt. MacDonald, and a priest stopped for a traffic violation who wants to have a drug dealer arrested for selling him marijuana.

The radical Robin Saydo on the loose, tied into a number of bombings. Reed spots him and Saydo is arrested by D.A. Paul Ryan. Other calls include an abandoned police cruiser which turned out to be a lone policeman on a foot pursuit capturing a drug suspect, and retired security officer Fred Tibbles assists the officers in breaking up a truck theft ring which took the trucks but not the merchandise within them. Note: This episode begins a crossover with The D.A. that concludes on "The People vs. Robin Saydo".

1-Adam-12 is back on the streets after routine maintenance, but the radio isn't working properly. During an armed robbery involving two suspects, Reed captures one while Malloy takes off in pursuit of the other one through Griffith Park and loses control of the car, and it rolls into an embankment hidden from the road, with Malloy suffering severe internal bleeding and a broken leg. All available units are called in to search for Malloy, who has to watch helplessly while a suspect hiding in the park takes his shotgun (which Malloy was using as a splint for his leg) and sidearm, and tears off the radio microphone leaving only leaving the wires. Malloy uses the wires to send a signal for help, which Reed picks up and is able to rescue his partner.

A man named "The Ferret" is vandalizing a manufacturing plant due to their poor record on ecology, and escapes Reed easily on foot pursuit. A reporter catches Reed in an unflattering light after the escape and plasters him over the front page. Reed is redeemed when he catches the Ferret when he returns later to the same plant and dumps a bucket of waste in the lobby. Other calls include a man whose pregnant wife fell into a coma after eating mud given to her by a voodoo priest, resulting in her baby boy being stillborn (when the officers confront the priest, he puts a mojo hex on Reed), and an elderly lady pulled over for a traffic violation who thinks the policemen are gas station attendants.

Truancy is on the rise in the district and Reed has a plan to pick up truants on the street, which was approved after a garage break-in by two truants. Results show a drop in crimes committed by truants, in one case two truants were stopped by the police and were implicated in a burglary, and one of the two truants involved in the garage break-in is brought in on another incident. Other incidents include arresting two heroin smugglers who hid the stash in their car's gas tank, which leaked some of the contraband making the car stall, and stop car thieves from stripping parts to build a dune buggy. Starting with this episode, Officer Ed Wells is promoted to Police Officer III (just under Malloy's rank of Police Officer III+1).

Malloy and Reed are sent to assist the Los Angeles County Sheriff's Department with transporting a prisoner from Malibu to Los Angeles for outstanding traffic warrants. During the trip, the prisoner reveals he is also a witness in a mob murder and a hit has been ordered on him. Suddenly, the cruiser is ambushed on a rural road, a tire is shot out, and they crash on a dirt road out of radio range. Reed is captured by hitmen attempting to get assistance, but Malloy and the prisoner steal the hitmen's car to get to a phone. The LAPD sends a police helicopter to search for Reed, who ends up overpowering the hit men and are captured.

Sgt. MacDonald's anniversary is coming up and the officers have limited funds to spend on a gift, which is a bottle of champagne, but when the officers pick it up, the owner of the liquor store was shot in an attempted robbery. Malloy and Reed later find the robber dead in a park from a gunshot wound inflicted by the owner. Other incidents include a paralyzed ex-wrestler tearing up a bar, a man driving suspiciously turns out to be the proud owner of several traffic tickets in a 24 hour period, a used car dealer trying to take advantage of a Mexican customer who speaks little English, and two camper thieves pushing a truck with a camper that is too small for the truck bed.

Over the course of their shift, Malloy and Reed deal with a racist gas station owner who is tired of being the victim of repeated robberies. When they catch the suspect, supposedly a black man, they find he is actually just an equally-racist white man in blackface. Other calls include a hitchhiker who extorts money from drivers she leaves in embarrassing situations, and a drunk who is seeing pink elephants.

A phony prowler call results in shots being fired at Malloy and Reed. Shots ring out again when the officers head to the airport to transport a blood donor. The suspect is a known check bouncer, and Reed's wife gets a disturbing phone call. Later Reed heads home and meets an acquaintance who just happens to be driving the same car as the shooting suspect. Other cases include a suicidal man who tries to incinerate himself with gasoline, and a wino who is nearly shot by Reed.

Officer Art McCall returns from eight years on disability and rides with Malloy and Reed to see how much has changed in law enforcement. McCall soon learns exactly how much has changed when he tries illegal techniques to help a young woman with her ex-con husband, fails to Mirandize a boy after arresting him for robbery, and screws up an arrest of a gun-carrying man who later plants a bomb in his ex-wife's car, which requires Malloy to dress down the veteran officer on his use of antiquated (and illegal) police procedures.

Malloy and Reed find a girl who was raped and left for dead in the hills but was actually alive and identified her attacker's car as a red Porsche. Malloy spots the suspect car picking up another girl and gives chase, only to have the suspect dump the girl on the street and the officer loses the car. Later the girl's mother finds drugs in the laundry and determine she was selling and the "rapist" was her supplier, while the real rapist is caught when he checked out of the hospital after being hit by his victim's heavy purse. The officers also handle a robbery at a construction yard foiled by police scouts.

Cases include a woman whose purse was robbed after two men bumped her car while on the road, then are captured along with the loot when a citizen complains about loud noise coming from their lair. A broken-down car leads to a meeting between the car's owner and a counterfeiter, and a fight in a fast-food restaurant results in an arrest of one of the combatants on outstanding warrants.

A disturbance call leads the officers to a nightclub where a singer named Kathy is strung out on drugs, and clings to Reed on the way to the hospital, telling him someone is trying to kill her and give her drugs. Narcotic detectives decide to assign Reed undercover as an AWOL soldier with a large stash of heroin to sell. Reed makes a deal, but Kathy blows his cover, and Malloy saves his partner from being killed and helps bring down the dealers.

Malloy and Reed deal with a woman who thinks she has a rattlesnake in her luggage, an out-of-town traffic violator, and a bar brawl, all while tackling armored truck robbers whose attacks have been predicted in advance by an informant.

Malloy is told that the best player on the recreational league basketball team he coaches has begun using narcotics again, which he flatly denies despite evidence to the contrary. He and Reed also search for a hit-and-run driver who struck a child, and pull over a driver with a seemingly disrespectful and wanted passenger.

Malloy and Reed investigate the ransacking of a college football locker room and uncover a controversial performance enhancing drug program. They also investigate suspicious parents who backtrack after their maid reports their baby as missing, apprehend a reported prowler who is then suspiciously let into the home by the female accuser and engage in a bullet-riddled high speed chase through a residential area.

A young girl from Chinatown is ordered by her father to withhold information from Malloy and Reed regarding her boyfriend, an undercover cop left in a coma after investigating a potential attack on a Chinese elders' association. Meanwhile, the officers also encounter a middle-aged marijuana user and a cross-dressing criminal who leads them to a counterfeit money ring while trying to pay his lawyer.

On temporary assignment at LAX, Reed and Malloy have to save a stewardess who is taken hostage inside a lounge by a man desperately trying to get the attention of a television producer. Afterward, they go undercover as rental car employees to intercept a large narcotics delivery from Toledo, and then try to identify and apprehend a rape suspect before he's able to escape on a flight.

Malloy tries to prove Sgt. MacDonald's innocence when Mac accidentally hits and kills a jaywalker while driving his police cruiser. Every witness on the sidewalk claims she was in the crosswalk, and the burglary suspect MacDonald is transporting is unmotivated to testify on his behalf. The truth proves to be far more complicated than the officers realized.

Malloy and Reed work to curtail the rise in illegal street racing by working with the leaders of rival racing clubs and obtaining the legitimate use of a drag strip through a race promoter. Their work is threatened, along with an anticipated race between Reed and Officer Wells, when one of the racers resorts to sabotage.

Malloy and Reed search for a six-year-old boy who was apparently abducted while walking home from school, and later fear that an elderly witness's wildly inaccurate account may actually pertain to a different crime. They also respond to a barking dog complaint and become suspicious of the dog's owner, mediate a domestic dispute caused by a husband's obsession with watching football, respond to a very creative college prank and pursue armed robbery suspects through a crowded train depot with the aid of a police helicopter.

Reed becomes preoccupied with the well being of a friend, an electrical engineer by profession, who has just qualified as a reserve police officer and has the bad luck of drawing Officer Wells as his partner. On patrol, Reed and Malloy help out a group of distrusting young adults who are planning to illegally camp in a public park after a rock concert, pull over a young couple in a stolen car and aid wells and the reservist in the foot chase of a heavily armed man who has been coercing innocent strangers into committing bank robberies.
