The story follows a fundamentalist sect of First Church of Latter Day Saints of which member BeckyLyn (Wettig) is a member. She is accused of killing her husband. Queenie (Leigh), another wife in the sect, doesn’t believe BeckyLyn is guilty and reaches out to her ex-communicated son, Jordan (Czuchry), for help. But when Queenie and Jordan start asking questions about the night of the murder, they quickly see all is not what it seems.
