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. (thetvdb.com)
