Trinity Is Still My Name - Enzo Barboni

A couple of two-bit thieving brothers try and keep a promise to their dying father: stick together and become successful outlaws. Bambino reluctantly agrees to show younger Trinity the ropes, but their gentle demeanors tend to diminish their haul by repeatedly helping the selfsame family they initially held up. Fun ensues in town and at the local Spanish mission where they are taken for federal agents, mistakenly so identified by Trinity's young love interest, daughter of the aforementioned family.
