Middle school history teacher Tom Robinson lives in Las Vegas Valley 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 Coyotaje and one of the Illegal immigration. 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.
