The creator of the three parts of "Piła" - Darren Lynn Bousman returns with an ominous revelation of horror movies, the sacred horror movie "St. Agatha ". The director's latest film is a real, "fearful roller coaster of fear" (Bloody Disgusting) with a stuffy atmosphere like incense and black as a monastic habit. It is a film that will give chills and heart palpitations to even the hardest lovers of horror movies. Cross the gate of God's forgotten monastery and take a desperate fight to save the soul. Mary (debuting on the big screen of Sabrina Kern) - a young pregnant woman is looking for a shelter in a monastery in the province of Georgia. The nuns receive her and promise help, but in return expect ruthless observance of the rules of the assembly and the renunciation of corruption brought about by the "external world." Mary agrees to these conditions, seeing in the monastery the perfect place for the birth of a child. With time, however, what seemed like a safe refuge begins to reveal its true, terrifying nature. Will Mary, persecuted by the specters of the past and unable to trust anyone, find the strength to free herself from the control of the demonic mother Superior (Carolyn Hennesy) and save her soul and the unborn child?
