About St. Agatha
Set in a quiet Georgia town during the 1950s, St. Agatha follows a pregnant con artist on the run who seeks shelter behind the stone walls of a secluded convent. What begins as a chance refuge to hide her unborn child soon curdles into a chilling trap where silence is enforced and every corner seems watched. The sisters keep to themselves and the convent hides more than prayer; strange rituals, strict rules, and a veil of secrets hang over the halls. As fear intensifies, Mary faces tests of nerve and grit, and she must find a way to protect her baby while the convent's dark agenda closes in. Escape feels possible, but freedom has a price.
Directed by Darren Lynn Bousman, the movie builds a lean tense atmosphere with a compact cast. The screenplay comes from Andy Demetrio, Shaun Fletcher and Sara Sometti Michaels, and Sabrina Kern leads as Mary alongside Carolyn Hennesy and Courtney Halverson.
Critics offered mixed takes, noting a patient mood and a claustrophobic soundscape that keeps dread close. The themes circle motherhood under pressure, autonomy versus control, and the price of secrets in a closed world. While not universally praised, the film earns respect for its nerve and clarity, delivering a stark meditation on faith, fear, and resilience inside a fortress of silence.
Box office receipts for St. Agatha clocked in at about 1.47 million dollars worldwide, a modest haul reflecting its niche release and genre appeal. The film found its audience mainly among horror viewers seeking a tense confinement story.
St. Agatha has a modest footprint in horror culture, resonating with fans who enjoy writers room style thrillers and claustrophobic settings. Its strongest echoes come through visuals of the convent and the eerie insistence on silence, which echo in later indie thrillers about trapped protagonists. For many viewers, the movie serves as a tight reminder that strength can emerge under pressure.
