After beginning the search for a well known suspect who just stole a 600-pound offset printing press, Reed and Malloy try to convince an 85-year-old man to leave the soon-to-be demolished apartment building where he's resided alone for 27 years. Afterward, they pull over a very unusual vehicle, and chase a delivery truck to the end of an unfinished bridge.

The radical Robin Saydo on the loose, tied into a number of bombings. Reed spots him and Saydo is arrested by D.A. Paul Ryan. Other calls include an abandoned police cruiser which turned out to be a lone policeman on a foot pursuit capturing a drug suspect, and retired security officer Fred Tibbles assists the officers in breaking up a truck theft ring which took the trucks but not the merchandise within them.

Note: This episode begins a crossover with The D.A. that concludes on "The People vs. Robin Saydo".

1-Adam-12 is back on the streets after routine maintenance, but the radio isn't working properly. During an armed robbery involving two suspects, Reed captures one while Malloy takes off in pursuit of the other one through Griffith Park and loses control of the car, and it rolls into an embankment hidden from the road, with Malloy suffering severe internal bleeding and a broken leg. All available units are called in to search for Malloy, who has to watch helplessly while a suspect hiding in the park takes his shotgun (which Malloy was using as a splint for his leg) and sidearm, and tears off the radio microphone leaving only leaving the wires. Malloy uses the wires to send a signal for help, which Reed picks up and is able to rescue his partner.

A man named "The Ferret" is vandalizing a manufacturing plant due to their poor record on ecology, and escapes Reed easily on foot pursuit. A reporter catches Reed in an unflattering light after the escape and plasters him over the front page. Reed is redeemed when he catches the Ferret when he returns later to the same plant and dumps a bucket of waste in the lobby. Other calls include a man whose pregnant wife fell into a coma after eating mud given to her by a voodoo priest, resulting in her baby boy being stillborn (when the officers confront the priest, he puts a mojo hex on Reed), and an elderly lady pulled over for a traffic violation who thinks the policemen are gas station attendants.

Malloy and Reed are sent to assist the Los Angeles County Sheriff's Department with transporting a prisoner from Malibu to Los Angeles for outstanding traffic warrants. During the trip, the prisoner reveals he is also a witness in a mob murder and a hit has been ordered on him. Suddenly, the cruiser is ambushed on a rural road, a tire is shot out, and they crash on a dirt road out of radio range. Reed is captured by hitmen attempting to get assistance, but Malloy and the prisoner steal the hitmen's car to get to a phone. The LAPD sends a police helicopter to search for Reed, who ends up overpowering the hit men and are captured.

A disturbance call leads the officers to a nightclub where a singer named Kathy is strung out on drugs, and clings to Reed on the way to the hospital, telling him someone is trying to kill her and give her drugs. Narcotic detectives decide to assign Reed undercover as an AWOL soldier with a large stash of heroin to sell. Reed makes a deal, but Kathy blows his cover, and Malloy saves his partner from being killed and helps bring down the dealers.

A young girl from Chinatown is ordered by her father to withhold information from Malloy and Reed regarding her boyfriend, an undercover cop left in a coma after investigating a potential attack on a Chinese elders' association. Meanwhile, the officers also encounter a middle-aged marijuana user and a cross-dressing criminal who leads them to a counterfeit money ring while trying to pay his lawyer.

Malloy tries to prove Sgt. MacDonald's innocence when Mac accidentally hits and kills a jaywalker while driving his police cruiser. Every witness on the sidewalk claims she was in the crosswalk, and the burglary suspect MacDonald is transporting is unmotivated to testify on his behalf. The truth proves to be far more complicated than the officers realized.

Reed becomes preoccupied with the well being of a friend, an electrical engineer by profession, who has just qualified as a reserve police officer and has the bad luck of drawing Officer Wells as his partner. On patrol, Reed and Malloy help out a group of distrusting young adults who are planning to illegally camp in a public park after a rock concert, pull over a young couple in a stolen car and aid wells and the reservist in the foot chase of a heavily armed man who has been coercing innocent strangers into committing bank robberies.

Malloy finds himself attracted to the new girl in the steno pool, and decides to ask her on a date after learning she's Officer Wells' 25-year-old niece. Out on patrol, he and Reed investigate a report of a prowler in a heavily wooded neighborhood, make a deal with a flower vendor before booking him for unpaid tickets, engage in a high-speed pursuit with a green corvette and investigate a suspicious gardener.

Officer Charlie Burnside pulls a prank on Officer Albert Porter, a friend of Reed's. Porter, who does not find the prank funny, informs Reed that Burnside is frequently "badge-heavy" (rough) with his suspects. After dealing with an inept would-be robber, Malloy and Reed observe Burnside choking a suspect. Reed reports the incident, but nothing is done by the Captain because the victim would not admit Burnside was the aggressor. Burnside turns cocky on Reed saying he has "an ace in the hole" and that Reed was mad about the prank he pulled on Porter, but it is later revealed that Burnside got to one of the robbers, placing him under investigation. At the end of watch, Burnside tries intimidating Reed, then tries brushing his intimidation off as a joke when he realizes the other officers are against him; when they all walk out, Burnside resigns.

During Malloy's birthday, he lets Reed know he does not enjoy surprise parties, but becomes increasingly suspicious and believes the others are actually planning a surprise party, much to his chagrin; it is soon revealed that is not the case. Meanwhile, Sgt. MacDonald warns the officers about a rash of robberies using milk crates to break store windows; during a routine traffic stop, Reed notices a milk crate in the back of a car and surreptitiously marks it for identification later, and the thief is apprehended later using the same milk crate. Calls include a backup call for a jewelry store robbery when the officers pull over the owner of said store for DUI, an embarrassed male purse snatching victim inside a negligee shop, a phony gas station worker at a closed gas station, a shootout in the police garage between the entire station and a drunk suspect officers failed to handcuff, and Officer Wells capturing a B&E suspect based on a hunch by Malloy.

Reed spreads his flu to several other officers, leaving the station undermanned. Calls include a shootout with a rifle-toting bookie, an argument between a storekeeper and a customer over a cantaloupe during an unrelated traffic stop, Reed locating a burglar after seeing a flashlight inside a store, and a teenager evading Reed in a foot pursuit. Due to the understaffing situation, Malloy and Reed are asked to do double shifts, and Malloy tickets a woman for turning right at a red without stopping. Later, Sgt. MacDonald assigns them to drive around a police commissioner for the night; the commissioner is actually the woman Malloy ticketed.

While on second shift, Malloy and Reed take Police Commissioner Dixon on a ride-along. They encounter a bar owner who locked a naked, elderly man inside, a fight with a knife-wielding man and another man with a gun, and a missing 17-year-old deaf boy with mental instabilities, which Reed recognizes as the boy that escaped his foot pursuit in the previous episode.

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.
