Gabriel and Elias, two old friends tired of their misfortune, have decided to carry out a plan that will change the course of their lives, and will serve as a lesson to the man who personifies their frustrations: a successful and corrupt businessman that just married Sofía, Gabriel's former couple.

Jerry Welbach, a reluctant bagman, has been given two ultimatums: The first is from his mob boss to travel to Mexico and retrieve a priceless antique pistol, known as "the Mexican"... or suffer the consequences. The second is from his girlfriend Samantha to end his association with the mob. Jerry figures alive and in trouble with Samantha is better than the more permanent alternative, so he heads south of the border.
