A clean-cut teenager tries to save his youth club from a greedy tycoon who wants to demolish it and build an office block by recording a hit pop single. Musical, starring Cliff Richard, Robert Morley, Melvyn Hayes, Richard O'Sullivan and Carole Gray and the rest of the Shadows.

Nicky and his friends find that their youth club is in danger of being flattened to make way for a new office block unless they can come up with £1500 to pay the new owner, the ruthless property tycoon Hamilton Black. To help raise the cash, Nicky records a song and his friends broadcast it via a pirate radio station, touting him as "The Mystery Singer" - the plan works and interest in their up and coming show is heightened by this new but unknown heart-throb. But Nicky has an even bigger secret and one that he cannot share, even with his girlfriend Toni... Hamilton Black is his father.
