“Can I see your cabbages?” Catholic priest David (Paapa Essiedu) questions the devoted nun Anna (Keeley Hawes). “Only if you get me drunk,” he laughs. And with that, a forbidden love story begins. This is Jack Thorne’s slow-burning new drama about the relationship between two churchgoers and their communities. In the opening episode, when Anna confesses her “immortal feelings of lust” to David, he doesn’t respond as expected – but it will force him to rethink his whole life. Does she really want to start over outside the convent? And are his thoughts on Hot Priest 2.0 one-sided? Jason Watkins and Niamh Cusack also star. Hollie Richardson
