It's A Sin, Episodes 1 & 2

Set in 1981, Ritchie (Olly Alexander), Roscoe (Omari Douglas) and Colin (Callum Scott Howells) are young lads, strangers at first, leaving home at 18 and heading off to London with hope and ambition and joy… and walking straight into a virus that most of the world ignores. Year by year, episode by episode, crossing the whole decade, their lives change as the mystery of that illness starts as a rumor, then a threat, then a terror, and then something that binds them together in the fight.
