85A tracks a watershed day in the life of an adolescent antihero. Foulmouthed with a capital F-word, Seamus embodies Johnny Rotten as a way of fending off the bullies at home, at school and in his whites-only neighborhood. Luckily, his mixed-raced friend Tressa opens him up to experiences that turn his worldview on its head. Through it all, Seamus basks in BBC dramas, dreaming of what life would be if only he could stow away to London. By the time Seamus reaches his last L stop, he will come to see that his 85A ride that morning was just the kickoff to an intrepid urban odyssey.
