A businessman who flew in from Los Angeles (the time it takes to fly from L.A. to S.F. is the source of the title) for a convention meets a woman at the convention center and agrees to join her on her houseboat in nearby Sausalito. They get into an argument and he winds up striking her on the head and fleeing. The woman's boyfriend gets home, gets into an argument with her and again bashes her on the head, killing her. The businessman is the prime suspect in the murder because he was seen arriving at and then fleeing the crime scene.

Stone and Keller handle a murder in Marin County. They are San Francisco policemen and Marin is not their jurisdiction (it's a different county). Even if the murder was in unincorporated Marin County, it would be handled by the Marin County Sheriff's office. Another officer seems to be at the scene, but he does not do any of the interviewing and disappears from the show. See more
