Welcome to England, 1809. London is a violent, intolerant city, exhausted by years of war, beset by soaring prices and political tensions. By day, John Church preaches on the radical possibilities of love to a multicultural, working-class congregation in Southwark. But by night, he crosses the river to the secret and glamorous world of a gay molly house on Vere Street, where ordinary men reinvent themselves as funny, flirtatious drag queens and rent boys cavort with labourers and princes alike. There, Church becomes the first minister to offer marriages between men, at enormous risk.

Everything changes when Church meets the unworldly and free-thinking Ned, part of a group of African activist abolitionists who attend his chapel. The two bond over their broken childhoods, and Church falls obsessively in love with Ned's tender nature. In a fragile, colourful secret world under threat, Church's love for Ned takes him to the edge of reason.

Based on the incredible true story of one of the most important events in queer history, Radical Love is a sensuous and prescient story about gender and sexuality, and how the most vulnerable survive in dangerous times.
