New Channel 4 series explores forbidden love between nun and priest

Channel 4 has commissioned Falling, a six-part drama set to air in 2026 written by Jack Thorne that centres on a romantic relationship between a Catholic nun and a Catholic priest, with the narrative built around the violation of their sacred vows of celibacy.

Keeley Hawes stars as Anna, described in production materials as a “devoted nun”, and Paapa Essiedu stars as David, a Catholic priest. 

The series, produced by The Forge Entertainment for Channel 4, follows the two characters who are “deeply committed to their work in the Church and in their community” but “unexpectedly fall in love”, forcing them to confront the consequences for their vows and their relationship with God. 

The trailer released in April 2026 uses the tagline “Lead us not into temptation” and promotes the project as a “forbidden love story”.
