A string of deaths at a convalescence home leads the Chief to go undercover as a patient, whose two children (Fran Belding and Ed) hint that they wish he were "no longer their problem". It soon appears that violence and murder are considered due care by certain members of the staff.

Due to give evidence, the Chief discovers that there is a contract out on his life, and that the chosen killer is a highly dedicated man. Whilst the authorities see only the lethal killer, however, it seems that everybody has another side to their personality.

A parole officer famed for his hard line against drug pushers begins to fear for his life after a shooting. The line of suspects, however, as well as including one of his current clients, also seems to include that client's lawyer, and even the parole officer himself.

Mark's graduation from law school coincides with the arrest of a caretaker that he has befriended. Believing the man innocent, he finds the weight of the law stacked against him, and quickly becomes disillusioned with his new career. Should he turn his back on law altogether, though, or should he just find another way to devote himself to justice?

The Chief is in the bank when it is robbed by a gang of three men, planning to await the arrival of a payroll delivery truck.

Mark and his girlfriend come across a murder whilst on a date, but decide to defend the killer when it transpires that he acted in self defence. During the case the pair get married, and Ed decides to move in with the Chief in Mark's place.

A court case is put in jeopardy when it seems that the jury is irrevocably hung over its verdict; until the Chief realises that one member must surely be on the take. He has a race against time to unmask the guilty party, however, before the judge must dismiss the jury and let the defendant walk free.

The teenage son of a friend of Fran's appears to commit suicide, however the evidence seems to point in a number of different directions. Did he kill himself, or was it a murder made to look like suicide? Or, alternatively, was a suicide made to look like it could have been murder? The Chief has to unravel the story, but he has little real evidence to help him along.

A girl thought to have died years previously turns up at the home of her mother just as her brother is found murdered. Clearly somebody is trying to kill the family off, but is it connected to the girl, and is she really who she says she is?

A man dies of a heart attack whilst flying his plane, but the town medical examiner, a charmingly eccentric Cuban doctor, is convinced that there was foul play.

An ingenious art theft takes place at Comus Towers Art Museum, and a guard is murdered in the process. Chief Ironside takes the case, but another death is to follow; this time the proprietor of the museum, who is an old friend of the Chief's.

A compulsive (and unlucky) gambler is in debt to a local mobster for $32,000. Ironside wants to put the mobster away, but only can if the gambler is prepared to turn state's evidence. The Chief has to persuade him to turn against the man who is offering him a way out of debt. (NB - The second episode to feature original song From The Day You're Born.)

When a drug pusher is arrested following a spate of botched drug raids he fingers Ironside as a gang informer. Ed is press-ganged onto a team set up to investigate the Chief, which leads to conflict with Eve. Meanwhile Ironside himself seems to be taking the investigation very calmly, which leads to concern all round.

A string of bank robberies are being committed, all with the exact hallmarks of a certain thief recently released from prison. Having a liking for the ex-con, however, the Chief wishes to believe in his innocence, and sets out to prove that it may be a copycat who is responsible for the raids.

The small daughter of a friend of the Chief's dabbles in witchcraft, and becomes convinced that she is responsible for the death of her parents' landlord. Taking to the case to show her that the truth is otherwise, Ironside discovers that the man arrested for causing the death might be equally innocent.

When a woman crashes her car into the Chief's van after suffering a minor heart attack, doctors discover a bullet lodged in her chest, where it has apparently been for several years. When she claims to have no knowledge of ever being shot, the Chief investigates, and soon links her case to that of an unsolved murder.

A policeman known to Ironside for some years is shot dead whilst on an investigation. The evidence points to him being crooked, but the Chief is determined to prove otherwise.

Cars are being stolen in worryingly high numbers, and with the numbers recovered falling dramatically, the signs point to a crooked cop somewhere in the department. Mark is convinced that the cop in question is innocent, but nobody else seems very sure.

A military-issue fragmentation grenade is used in an attack on two Vietnam veterans, one of whom - a friend of Mark's - is killed. When it transpires that another of the pair's old unit has come under similar attack, the Chief sets out to trap the killer, using Ed in a cunning disguise as bait.

The star witness to a major case, Ed is shot and seriously injured by a mystery assailant. Threatened with paralysis he conducts his own struggle from within his hospital bed, whilst the Chief tries to find out who is still trying to kill his prize pupil. Meanwhile Ed's best chance of recovery is an untested experimental operation performed by a surgeon whose integrity is very likely about to be put to the test. The crossover continues on The Bold Ones: The New Doctors S04E01 Five Days in the Death of Sgt. Brown (II).

A scientist is given a irremovable belt containing explosives, and the man responsible demands the release of three men from prison in return for the key to the device. The Chief sets out to find and trap the man before time runs out and the bomb explodes, taking an innocent person with it.

The promotion of a new Chief of Police leaves an opening for a new Chief of Detectives, and the front runner for the job is Lieutenant Amy Prentiss. Much of the force is opposed to her appointment, but she is determined to prove them wrong. With Ironside and his team alone in supporting her, she has to make her mark in a difficult case beset with problems, whilst at the same time convincing her male dominated staff to accept her as their new leader.
