London, the early 1980s: a group of young friends is chasing freedom, romance and fun just as a new and terrifying illness starts moving quietly through their circle.

What is It's a Sin about?

Ritchie, Roscoe, Colin and Jill build a life together in a shared flat they nickname the Pink Palace, throwing themselves into a decade of nightlife, ambition and self-discovery. As the years pass, whispers of a mysterious illness affecting gay men grow louder, first dismissed and then impossible to ignore, forcing the group to confront fear, stigma and loss inside a society slow to acknowledge what is happening around it. The story follows their friendship across ten years, weighing the joy of finding each other against the toll a spreading crisis takes on all of their lives, and on the families some of them keep at arm's length.

About the cast

Olly Alexander leads as Ritchie, with Omari Douglas as Roscoe, Callum Scott Howells as Colin, and Lydia West as Jill, the friend who becomes the group's steadiest anchor. Nathaniel Curtis rounds out the core cast as Ash, another member of the flat's tight circle.

Context & significance

Written by Russell T Davies and directed by Peter Hoar, the series draws on the real history of the AIDS crisis in Britain, folding personal memory into its portrait of the era. Its soundtrack and production design lean heavily on early-1980s British pop culture, grounding the friend group's story in a specific, recognizable moment before shifting into darker territory. The show was released in five weekly installments, a rollout that let its central relationships settle in the audience's mind before the crisis at its center fully arrives. That structure also gives the show room to shift tone gradually, moving from breezy comedy in its early episodes toward a much heavier register by its close.
