Malloy and Reed have to wear their long-sleeved uniforms despite a hot forecast, then learn they could have changed to short sleeves but missed the radio notification. Calls include the search for a bicycle pump that contains drugs, a woman experiencing withdrawal symptoms with the dealer and the pump up the street, a man complaining about his grass being trampled during his neighbor's yard sale (which had stolen property taken by the neighbor "on consignment") leads to the discovery of the burglar, who then provides a tip on a murder suspect.

Malloy's old landlady, Mrs. O'Brien, has her purse stolen and refuses to leave the station until her case is settled. Mrs. O'Brien resorts to other means, including hounding detectives and setting up a picket line to vent her frustrations. Malloy makes connection between her theft and a string of purse snatchings involving social security checks, and a decoy leads to the end of the theft ring. Calls include two suspicious men and a pursuit involving them, and a homicide where candy wrappers and tire tracks from the pursuit suspects are found.

Malloy and Reed pull over a car on a routine traffic stop and are taken hostage by two robbers escaping from their heist. The officers have to use all their skills to escape the situation.

Malloy and Reed are stunned to discover that the driver who led them on a high-speed chase is the son of Sgt. MacDonald, and Malloy takes it upon himself to help his boss figure out why the young man is acting out. In the meantime, they investigate a possible burglary in progress at an apartment building, mediate a dispute at a park over an elderly woman feeding ducks, respond to a call of two armed men fighting over a woman and deal with a wino who is attempting to direct traffic at a busy intersection.

Malloy and Reed patrol a neighborhood of Los Angeles inhabited by a large retired population. Calls include a purse snatching during which the suspect eluded capture, but was later found during routine patrol, an elderly man with multiple warrants for auto theft trying to break into a car in a church parking lot, a dispute between an elderly woman and man over her eviction and his offer to take her in (the woman is later arrested when she begins smashing 1-Adam-12's windshield with a baseball bat), a dispute over $5, a baby stroller rolling into a lake, and a retired policeman-turned-security guard named George who wants to talk shop, then assists in the suspects' arrest after a robbery, afterwards laments to the officers about being lonely due to all of his friends passing on.

Malloy and Reed have to break the news to a young model that her press agent lied when he said there would be nothing wrong with having a nude photo shoot on a busy public beach. Later, they discover a man stealing from a phone booth, assist in the chase of a stolen dune buggy, try help an attractive woman whose safety is put in grave danger by an obscene phone caller, deal with a wino who dies while eating at a diner and pull over a woman towing a large jack-o-lantern.

Reno West's burglary reign continues, and the Captain orders it stopped at all costs. Other cases include having to divert a vicious guard dog so the officers can save a 70 year old man in a diabetic coma, investigate a theft of a rare jade statue from a mansion, and a domestic dispute between a couple where it appears the wife is the abuser.

While Reed is having his shoes fixed at the repair shop, the squeakiness of his replacement shoes is driving Malloy crazy. On patrol, they deal with a deranged homeowner destroying his own possessions, stop a cargo van whose driver misunderstands the meaning of double jeopardy, search for a young boy hiding in an industrial building about to be demolished and create a hostage situation after shooting a bank robber.

Reed and Malloy respond to a dispute in a park, where elderly woman Edna Digby (Lillian Bronson) tries to stop painter Andre Pochek from selling a painting that she considers indecent. To resolve the issue (due to the seller needing a new permit and being short on money) Malloy buys the painting and puts it in the back of the cruiser. It becomes a frequent topic of discussion despite Malloy's dislike for the painting, and when Malloy tries to sell it to another officer, the officer only buys the frame, leaving him with the painting. Calls include a man trying to retrieve a valuable coin from a toy dispenser, a potential "peeping tom" who is actually a city employee using a telescope to check meters to avoid dogs, a repo man trying to widen a door in a house he is trying to repossess furniture from, and an ex-football star-turned-robber who flees into the Los Angeles Memorial Coliseum.

Reed volunteers to write a profile on Malloy for the LAPD's magazine to honor his 10th anniversary on the force, but soon discovers he may be in over his head. Out on patrol, an apparent gas station armed robbery gets turned on its head when they question the parties after a long chase, a man goes to extreme lengths to get his neighbor's poodle to stop barking, a woman's plan to get her husband arrested backfires and a liquor store robbery suspect barricades himself inside a house's garage after a high-speed chase.

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.

As part of a trial program, Malloy and Reed team with Motor Officer Grant to better combat crime. Out on patrol, they make a safety check at a residence, investigate a suspicious witness at the scene of a traffic accident, deal with a young member of a neighborhood watch, respond to an annoying complaint about illegally parked cars and perform a daylight stakeout to catch a serial burglar.

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.
