In Britain 1966 recently expelled student, Carl has been sent by his mother to find some direction in life by visiting his godfather, Quentin. However, Quentin is the boss of Radio Rock, a pirate radio station in the middle of the North Sea, populated by an eclectic crew of rock-and-roll deejays. Life on the North Sea is eventful. Carl discovers the opposite sex and who his real father is. Meanwhile, pirate stations have come to the attention of government minister Dormand, who is out for the blood of these lawbreakers. In an era when the stuffy corridors of power stifle anything approaching youthful exuberance, Dormand seizes the chance to score a political goal, and The Marine Broadcasting Offences Act is passed in an effort to outlaw the pirates and to remove their ghastly influence from the land once and for all. What results is a literal storm on the high seas. With Radio Rock in peril, its devoted fans rally together and stage an epic Dunkirk-style hundred-boat rescue to save their deejay heroes. Some things may come to an end, but rock and roll never dies.
