"He's the witness. His family is the target."

Jeff Corrigan has to enter the witness protection program with his family when he gives up his former boss to the FBI after discovering that he is a drug lord. Relocating his wife and kids causes trouble for them, as they are very dissatisfied with their new lives. Unfortunately, the protection program also fails, as the gang tracks down the family and Jeff is forced to protect them from attack.
