I quattro dell'Apocalisse

Stubby Preston (Fabio Testi) and his companions, Bunny (Lynne Frederick), Clem (Michael J. Pollard), and Bud (Harry Baird), escape the law after a vigilante attack on a casino in the Wild West town of Salt Flats, Utah. Along the way, they encounter a group of Quaker immigrants and witness a violent bandit raid, before being taken in by a wanderer named Chaco (Tomas Milian), who tortures and rapes Bunny. After Chaco's cohorts are killed, the four continue their journey, with Clem dying from infection and Bud descending into madness. Stubby and Bunny eventually find shelter in a ghost town, where they confess their love and have sex, and later, Stubby adopts the child of the deceased Bunny, named Lucky.
