Paul is a young assistant to Senator Kitteredge. He is entrusted with a special mission: accompany Robin, the Senator's feisty daughter to a psychiatric clinic where her father wants to lock her up. This mission means several days travel in the Senator's Mercedes and Paul wants to bring his best friend T.S. When he meets the young girl Paul realises she will be trouble and two men are just enough to escort her. Robin tries to escape from the car and then tries to hitch a ride with a trucker. Finally Paul gives in and helps the girl find her mother. The family reunion doesn't go as well as they had hoped and the three friends get back on the road.
