On a hot Texas summer night in 1989, family man Richard Dane (Dexter’s Michael C. Hall) awakens to the sound of a burglar breaking into his home. In a panic, he shoots the intruder dead—but this nightmare is only just beginning. Although he’s hailed as a small-town hero, Dane soon finds himself fearing for his family’s safety when the burglar’s ex-con father, Ben (Sam Shepard), rolls into town; hell-bent on revenge. However, not all is as it seems. Misled by the cops and desperate for answers, Richard embarks on an increasingly berserk, bloodstained quest to discover what really happened that night.
