Kate Bennett has spent most of her life shielding her sisters from their angry mother. A loner, she's an easy recruit for a zealous youth group at her high school. On her first visit to The Ark-the group's headquarters-Kate hears a sermon she can't ignore.

Full of passion, Kate announces to her family that she's joining The Ark. Her mother's rage erupts, and she tells Kate that she's been brainwashed and forbids her from ever mentioning "that cult" again.

Despite her mother's warning, Kate can't deny her calling and flees her dysfunctional family. The Ark's charismatic leader welcomes her with kindness and open arms. As she becomes close to those in The Ark's inner circle, Kate believes she's found everything she needs. But doubts arise when Kate learns the sins and secrets of those she's trusted the most. Is this a godly refuge or was her mother right?
