"St. Agatha" is set in 1950’s Georgia, and fixes on a pregnant con woman who is on the run and seeks refuge in a convent. However, what first starts out as the perfect place to have a child turns into a dark lair where silence is forced, ghastly secrets are masked, and every bit of will power Agatha has is tested as she learns the sick and twisted truth of the convent and the odd people that lurk inside its halls.
