Officer Malloy pays tribute to Officer Tom Porter, who has recently fallen in the line of duty. Malloy recounts the close friendship they developed while training at the academy, as well as the moments where they crossed paths on duty, including the night of the officer's unfortunate demise.

An 'officer needs help' call comes in with no callsign or location. The dispatcher starts a division wide radio "roll-call" in order to account for every officer on patrol. While the roll-call is going on, calls for service from the public still needs to be handled. When a motorcycle officer fails to check in when prompted, a division wide search is instituted to look for him, which Malloy & Reed are assigned to assist in.

While on a quiet patrol, Reed decides to spend part of his lunch break doing business at his bank while Malloy waits in the patrol car. Unfortunately, he walks into the clutches of a pair of ruthless robbers who take him hostage.

Malloy and Reed search for a six-year-old girl in a red sweater who was kidnapped. Malloy finds the girl in a neighbor's house – the neighbor has kidnapped and raped the girl, and she is unconscious. The perp attempts to escape, Malloy catches him and loses his cool when the suspect claims that the girl was "asking for it." The suspect files excessive force charges against Malloy, which he admits to; he knows he will be punished by his old mentor, Capt. Moore which may derail his ambition to become sergeant. Moore gives Malloy a four-day suspension for his actions. Other calls include rescuing a man who got stuck in the storm drain system.

Reed is suffering from a wrist injury which puts him on desk duty, while Malloy has to break in a new rookie partner. Reed's day is far from routine as he has to handle a bomb threat that results in the evacuation of the station, Officer Brinkman accidentally discharges his shotgun twice, a young man wants to report misconduct by a police officer, an elderly man brings a shotgun into the station to drop off, Malloy brings in a group of children abandoned by their mother, and Malloy and his partner pursue a car into the police parking lot, where the suspects are arrested.

Malloy and Reed begin today's patrol by responding to a call of a drunken woman threatening the patrons of a bar with a handgun. Afterwards, they search for a group of four carjackers who go on a robbery spree after targeting a man with a cache of guns in his trunk, and investigate the suspicious death of a mentally disabled man.

Malloy and Reed are on the lookout for a traveling business man driving a green pinto, who called his wife in Nebraska and told her he was going to commit suicide at 2 PM. Meanwhile, they search for a woman who abandoned her newborn baby in a garbage can, and get a tip from an elderly woman about a group of car strippers.

Malloy and Reed are the first to respond to a downtown rooftop sniper who has been indiscriminately shooting at anyone he can find with his scoped rifle. After risking their lives to get civilians out of his line of sight, they become lead participants in the S.W.A.T. team's attempt to neutralize the suspect.

Reed returns from an off-day with an uncomfortable full-body sunburn, which causes him problems throughout the watch. Calls include responding to a traffic accident, acting on a tip from an informant, busting a drug dealer working out of abandoned homes, searching for a robbery suspect based on a vehicle description, and assisting in the rescue of two boys when their boat capsizes.

Malloy tries to find a way to help a 60-year-old career criminal he arrested 10 years ago, who was recently released and begs to be re-arrested so he can spend his retirement years in the federal penitentiary. Meanwhile, he and Reed become suspicious while investigating an apparent home burglary, and later respond to a bank robbery in progress.

During their Christmas Eve Patrol, Malloy and Reed contemplate using their patrol car to deliver a Christmas tree to the residents of a soon-to-be-closed retirement home. Meanwhile, an elderly man's bagpipe playing is considered a public nuisance, a couple of teenagers steal a delivery truck containing radioactive material, a nervous man is desperate to cover up the smell of perfume on his clothing and an armed robbery suspect becomes intent on committing suicide-by-cop.

While paying a visit to the laundromat before going into work, Malloy encounters a man using the facilities to dry something much different from clothing. On patrol, he and Reed deal with a minister-in-training who uses a very unorthodox method to get his message across, try to reunite a Finnish-speaking child with her family, mediate a strange dispute between feuding neighbors and engage in a high-speed chase with a well known drug dealer.

Malloy and Reed respond to a fire where a young man, Lauro, saves a man trapped inside. But Lauro seems reluctant to receive any praise or attention much to everyone's surprise. Meanwhile, a concerned landlord reports suspicious in-activity from a tenant with heart trouble where Malloy and Reed arrive in time to give him CPR and save his life. Malloy attempts to keep his new hat clean, but finds it an impossibility.

Malloy and Reed prove they cannot and will not be bribed, no matter how good the offer, resulting in desperation from a young man charged with his third drunk driving offense. An elderly man admits mercy killing his wife.

Malloy returns from vacation sporting a mustache, prompting chuckles and guffaws from the squad. The officers then assist Air Ten in rescuing two people from an airplane crash. Reno West, a paroled thief, is suspected in the theft of some stamps from a mansion. A witness provides excellent descriptions of suspects involved in a jewelry store robbery. And a woman takes an alleged purse snatcher to the police station in her car rather than walk four miles to do so. Malloy shaves off the mustache when he has trouble trimming it.

Malloy's brand new car gets dinged up when he has to bail out to chase down a purse snatcher, but Sgt. MacDonald promises him his kid brother in Beverly Hills can fix it on the cheap. Out on patrol, he and Reed search for a drunk man accused of randomly shooting arrows, respond to a robbery at a deli that results in tragedy and search for a drug store robbery suspect who gets away after being shot.

Malloy, Reed, and Officer Woods are assigned airport duty at LAX, now equipped with closed-circuit cameras, which were used to observe a burglary in progress and apprehend the suspects before they could leave. An argument over a suitcase resulted in the discovery of drugs, another dispute involving an Army soldier and another man uncovers a scheme where the civilian took Japanese Yen from the soldier. A ticket clerk that catches Malloy's eye informs him of a man who bought tickets from her previously under a different name, which results in the breakup of a credit card theft ring, a runaway is escorted to security until his mother can pick him up, and a silent alarm at a toll gate results in the capture of a robber who was holding a hostage. As a reward for breaking up the credit card theft ring, the company invites Malloy and the ticket clerk to lunch—Reed is invited too but Malloy pays Reed (a week's worth of lunches) NOT to join the couple on the lunch date.

A burglar is on the loose, and the officers handle a call with a drunk who is nearly a dead-ringer for the burglar, later he ends up falling down at a bar where Officer Woods was handling a call regarding him. Other calls include looking for an antique stove an Asian woman gave away without knowing her husband had hid money inside it, getting an obese woman out of a phone booth, and a stakeout for the burglar mentioned at roll call resulting in his capture; during the pursuit, the charity truck that picked up the antique stove is located, and the money is returned to the family.

Malloy and Reed investigate a large car theft operation that targets older cars, then stages them around the city as abandoned vehicles so they can be towed and scrapped. Meanwhile, they try to figure out why the son of Malloy's girlfriend is getting bad grades, search for a suspect who robbed an elderly woman and attempt to rescue two foolish teenagers who enter a house that is being fumigated.

Malloy is kidnapped leaving the station by a drug runner and his female accomplice, demanding her boyfriend be released from jail in exchange for Malloy. When the couple has Malloy contact the station to confirm his status, he reveals a clue about where they found a girl with a mannequin (a reference to the episode "Citizen With Gun"). Reed finds Malloy's car and a citizen gives a description of Malloy's kidnappers and their car, which Reed finds abandoned but he locates their hideout from case files, meanwhile Malloy manages to spill gasoline and ignites it, allowing Malloy to be rescued by Reed who notices the gunfire and smoke.

A former convict and informant who Malloy helped give a second chance is accused of assaulting a priest, dealing drugs and stealing a gun after being fired from his dish-washing job at Duke's Longhorn Café. Malloy and Reed set out to determine if his story, which is full of suspicious coincidences, is actually true.

Malloy and Reed become envious of officer wells, who has been given a coveted assignment in the newly established astro helicopter division. Out on patrol, they require assistance saving a wealthy elderly couple who get locked in their heavily fortified basement safe, and then use air support to track down robbery suspects who escape on a motorcycle.

Malloy and Reed hope to find an impostor as they investigate a boxing promoter's accusation that a police detective stole $350 from him. In the meantime, they deal with a disgruntled wife who is in the process of destroying her own car in the middle of a downtown street, investigate a gun theft from a pawn shop, drive up on a home burglary in progress and obtain critical information while interrogating a suspected car thief.

Malloy fears that a boxer who has just been paroled after serving a murder sentence is going to seek revenge against him. Out on patrol, they try to save a man who has been crushed while working under a stolen car, apprehend a liquor store robber who swears revenge against reed, change a flat tire on their patrol car, locate a four-year-old child who locked himself in a refrigerator and become the targets of an ambush.

Malloy and Reed search for a suspect who frames an employee of a manufacturing plant for theft and then plants a powerful bomb on the premises. They also apprehend two criminals after questioning a suspicious man who is carrying heavy bags down the street, and protect an innocent motorist from a street race that still ends in tragedy.
