Terence Hill and Bud Spencer star in a double bill of spoof spaghetti westerns. In 'They Call Me Trinity' (1971), Trinity (Hill) is a scruffy drifter who discovers his half-brother Bambino (Spencer) posing as a town sheriff. When Mexican outlaws arrive and try to force a group of Mormons to leave, Trinity and Bambino intercede. Matters are further complicated when Trinity falls for two of the Mormon girls. In 'Trinity Is Still My Name' (1972), Trinity and Bambino forego their law enforcement duties and set out to honour their father's dying wish that they become successful bandits. However, the boys don't take easily to a life of crime and inadvertently end up rescuing a group of monks from a villainous gun-runner.
