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).
