A London opera house is haunted by tragic events on its opening night, but when its star is kidnapped, a producer tracks down the Phantom who is intent on seeking his revenge.

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.
