Alternative (1978)

A tourist bus is driving along the road. In front of him is a man who wants to tell the passengers something. On the bus are drunk men, a writer, an Arab sheikh, a prostitute, a priest, a hunter, a boxer, and a Japanese woman. None of them pays attention to the warning. They even mock the person and threaten him. Only when the bus falls into the abyss does it become clear that the person wanted to prevent the disaster.
