Amazon Prime Video has shared a teaser trailer for the romantic drama My Policeman, featuring singer and actor Harry Styles.

My Policeman is based on the Bethan Roberts novel of the same name. The story follows Tom Burgess (Styles), a closeted gay policeman living in Brighton, England, in 1957 when homosexuality was illegal. Tom starts publicly dating a schoolteacher, Marion (Emma Corrin), but embarks on a secret love affair with a museum curator, Patrick Hazelwood (David Dawson).

An official film description reads: “Based on the book by Bethan Roberts, director Michael Grandage carves a visually transporting, heart-stopping portrait of three people caught up in the shifting tides of history, liberty, and forgiveness.”

My Policeman opens in theaters Oct. 21 and will begin streaming Nov. 4 on Prime Video.
