The three head into the jungle, get in more than a few fights amongst themselves, and view lots of gratuitous animal cruelty, notable an iguana getting eviscerated.

An anonymous, but deadly man rides into a town torn by war between two factions, the Baxters and the Rojo’s. Instead of fleeing or dying, as most other would do, the man schemes to play the two sides off each other, getting rich in the bargain.
