Plot
Middle school history teacher Tom Robinson lives in Las Vegas with beloved wife Elizabeth. On a horse riding trip out in the desert one day, Elizabeth comes across a human trafficking deal gone bad, with gangster Jimmy Dolan executing the two Coyotes and one of the illegal aliens. Elizabeth is seen, however, and narrowly escapes Dolan's thugs firing at her. She drops her phone, which the thugs find and use to identify her. Soon afterward, a corpse with its lips sewn shut is left in Elizabeth's home, a threat to keep silent.
The Robinsons go to the authorities, and an official admits them into the Witness Protection Program. Elizabeth awakens one night, needing to vomit, which she takes as a positive sign that she is pregnant. Excited, she rushes out of their hotel to buy pregnancy tests, with Tom following her. When she tries to start their car, it explodes, killing her as Tom watches, stunned.
Devastated, Tom begins drinking, and eventually decides to seek revenge against Dolan. He purchases a handgun, a massive Smith & Wesson Model 500, and follows Dolan around town, eventually going after him one night. But before he can take the shot, a rival business of Dolan's pulls a drive-by, which fails because Dolan's Cadillac is revealed to be bulletproof.
