Twenty-four hours before she is set to exchange vows with the man of her dreams, a flustered bride-to-be wakes up next to a complete stranger who claims to be her husband in this south-of-the-border romantic comedy.

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.
