Moonlighting - Season 1 (1985)

Paul McCain reigns over late night AM talk radio, KRKD 1040. During the 2:00 to 6:00 o'clock a.m. time slot, listeners could call "The Heartbreak Hotline" at 555-HART to pour out their fears, hopes and dreams. One night, in the midst of a live broadcast, loud, violent staccatos of gunfire burst out across the air, stopping the voice of Paul McCain in mid-sentence. The resulting investigation receives attention and front page headlines; David immediately sees dollar signs; all Maddie sees is they have no client and she turns up her nose at the idea of lonely people ...

When Ms. DiPesto has won a competition, she is allowed to join a Le crime de l'Orient-Express (1974) inspired crime game in a train created by her favorite crime author. She is accompanied by Maddie and David to central station. Maddie and David miss to leave the train before it starts off and now have to stay on it since it won't stop for the next 24 hours. When a real murder happens, everybody is suspicious and the two detectives have to solve the crime.

David gets the agency a job collecting money from debtors, which he believes that it will be easy but Maddie is not so sure. They find themselves involved in murder, a disappearing body and an international conspiracy.
