Mods, rockers, new romantics, skinheads. It's the summer of 1983 and British youth culture is thriving. Margaret Thatcher is in office and it's a little more than a year after the Faulklands War, so there's a general conservatism to feel rebellious about. Twelve-year-old Shaun (Thomas Turgoose in his first acting role) is a lonely kid who still grieves for his dad who died in the Faulklands. His mom (Jo Hartley) cares for him but is a bit disconnected from his life. After suffering abuse from kids on the last day of school, Shaun encounters a gang of skinheads. Contrary to what we might expect, the leader, Woody (Joe Gilgun), turns out to be friendly and takes little Shaun under his wing.
