A group of theater actors travel across the country in a bus, promoting mambemb coups and collective orgies. Even the participation of a nun, who enters the vehicle and is received in a touching and affectionate way, receives special attention.

The trickster Smudge steals a bus at a gas station, abducts some employees and covers Brazil from São Paulo to Rio Grande do Sul in the vehicle, now renamed "Coach of Suruba" or "Ônibus de Suruba". Along the way, it forces the "passengers" to have sex.
