Two "Gunsmoke" writers teamed on this modern-day Western set at a rodeo in San Francisco's Cow Palace. A bronc rider dies in what appears to be an accident. A rodeo clown looks around the scene after the police leave and discovers the rider's rope -- which was cut almost halfway through before it broke, leaving the bronc free to throw him. The police come back to investigate the scene, and before long the chief suspect is also murdered in another "accident."
A team of angry fathers, who are fed up with crime in their neighborhood, take a vigilante approach at solving the problem. During one of their rampages, a police informant is killed and the murder is blamed on the group. The murder leads to a narcotics ring and Stone and Keller have to try to link the crimes together.
When a high-ranking hoodlum's son is found murdered he brings in the help of the adrogynously named "Sydney"--a hit woman who's assigned to murder the three thugs responsible. Stone an Keller are looking for them, too. Somehow Sydney becomes Keller's next door neighbor and a relationship develops during their investigation. When Stone & Keller discover two of the hoodlums have died before they can be brought into custody, Stone suspects the worse: his partner is sleeping with the killer. Sydney is played by Brenda Vaccaro, who at the time was married to Michael Douglas.
Set in a midtown hotel, "Labyrinth" tells the story of a prizefighter who was supposed to throw a fight but didn't. Some representatives from the mob meet him to "discuss the matter" in his hotel room. He ends up beating up one of the men and throws him out the window. He beats up the other two and is shot in the process, but not fatally. He runs from the room and holding the gun he hides in another room with an adulterous couple. Stone and Keller are called in to investigate the hit man's death. The race is on: who will find the prizefighter first--the cops or the hired muscle? Included in the cast of characters is a traumatized ex-cop who quit the force and became the hotel's head of security.
Against his will, Stone gets a new partner while Keller recovers from a gunshot wound. Hippie-haired narc Al Walczinsky isn't too happy about having Stone as a partner either.
