Drama starring Daniel Huttlestone as a teenager discovering London's punk music scene in 1979. 14-year-old Shay (Huttlestone) lives with his struggling father (Dougray Scott) in the suburbs of London and works part-time in his music shop, selling pianos. His life is instantly changed forever when his estranged mother (Natascha McElhone), who lives in the city, sends him a record by The Clash and he's immediately hooked by the power of punk rock. When he meets a young, like-minded individual listening to the band on the train, Shay becomes determined to get to London to experience all that the punk scene has to offer. Together, he and his new friend Vivian (Nell Williams) begin a wild adventure through the capital that leads them to a chance meeting with Shay's idol, Joe Strummer (Jonathan Rhys Meyers).
