Deputy Sheriff John Cronin and his granddaughter, Jesse, are preparing for Jesse's upcoming wedding to her Marine when the Cartel decides to murder some South Texas cops as a payback for arresting their drug smugglers. They send a hit squad to kill Cronin, Jesse, and everyone close to the family. The only problem? They missed the old man. Leaving his badge behind, John Cronin, Francisco and a few others head south to teach them a lesson about what old school western justice really means.
