Cold Comfort (1989)

Three lonely people depend on each other when they get stranded at a deserted gas station in a blizzard. Floyd is a truck driver balancing on the edge of lunacy. He is the caring father of 16-year old Dolores, but is also torn up by sexual feelings for his daughter. Sales rep. Steven also ends up in the blizzard with his car in a ditch. Floyd rescued Steven and brings him along as a birthday present for Dolores. In all the confusion Steven doesn't realize at first how he has become a prisoner. He is the pawn in a chess game between father and daughter which evolves in a matter of life and death.
