A thirteen year old boy is the only witness to his mother's murder, but finds it hard to co-operate with the Chief, knowing that it was Ironside who put his father in prison. Allowing Marty Jessup a temporary pass is the only way for the Chief to solve the murder and to lessen his conscience at the same time.

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.

An actor/producer is murdered during a series of comic improvisations, and all of the actors present at the time seem to be suspects. Given a number of aliases and false leads, the Chief embarks on the trail of the killer.

Whilst in London at a conference with the Chief, Ed witnesses an assassination, and promptly becomes the killer's next target. Meanwhile he and Ironside have to work with the local forces to find the assassin, but find themselves hampered by the Superintendent on the case, an old friend of the Chief's who seems to have a hidden agenda.

A robbery goes wrong and one of the thieves is killed, whilst another, an unlikely sort to be taking part in a robbery, is arrested. The third thief manages to escape with the money, but when the young daughter of the arrested gang member is kidnapped, the ransom being the unrecovered money from the heist, the team faces a race against time to capture the missing man.

The Chief's god-daughter witnesses a murder whilst performing in a street-side harlequin show. On the run from the murderer, she and her boyfriend remain one jump ahead of Ironside's team; but there is an added dimension to the case which the Chief cannot at first hope to guess at, and a further reason for his god-daughter's desperate flight.
