Hannah, a successful tech entrepreneur, decides to drop out of society and create a new social app, 'Know Me.' She's invited to test the app on a small religious community, the Church of Love and Devotion. The results go way beyond any intended consequences as lines separating the self, technology, and belief become blurred and lead to religious cult indoctrination. Loosely inspired by the life of the notorious Jim Jones and updated for the social media age, Holy Hannah explores family and the ways in which people's lives become intertwined in unexpected and toxic ways.
