Four couples in crisis attend a multi-faith Conjugal Love retreat. Each participant carries a very clear idea of what she hopes to achieve. However, the strange tasks ordered by the monitors continually disrupt personal plans. The confusion increases when the same monitors stop hiding their conflicts, forcing each participant to assume an unexpected responsibility despite the consequences.
Unfortunately the movie The Heretics is not yet available on HBO Max.
