Malloy and Reed then come up with and carry out an ultimately successful plan to nab the wanted criminal.

At the station, Malloy loses his cool while talking to Wells because Wells' tactics endanger his life and others.

Malloy and Reed are forced to rescue Wells and mastermind a way to end the standoff peacefully.

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.

A silent alarm at a shop results in the owner being shot and critically injured; one suspect is caught, the other escapes when Reed has to save a baby in a runaway carriage. The shooting puts the family in a financial crunch, which can be helped with paperwork from a new program to help victims of violent crimes, but none are available.

Amy Milner, Martin Milner's daughter, appears in the episode as the shop owner's daughter.

Malloy continues his assignment as acting Watch Commander, so Reed is paired with Officer Dana Hall, while Officers Wells and Woods treat the new policewoman with the typical (for the 1970s) "not the woman's place" attitude, Reed treats her with respect and they go on patrol, where they encounter an underage DUI suspect with an uncooperative mother, locate and search a car stripping operation, and arrest numerous young people who riot at an outdoor rock concert.
