Koji, a jazz musician, takes a cigarette break in between sets at a Tokyo nightclub. He witnesses a murder and runs into a girl, Linda, who is being pursued by the killers. For the next two hours, Koji and Linda are running from both the hitmen and the police. Mistakenly identified as prime suspects, they have to solve the crime but time is running out: Koji has to be back to perform in his club by midnight, as a very special guest will be attending.
