Twenty years after the original film Gregory’s Girl, Gregory Underwood is now 35 and back at his old school, teaching English and preaching against political corruption and the abuse of human rights. When two of his pupils uncover corrupt practices at a local factory, they want Gregory to help them expose the wrong-doer, who happens to be his old school friend. Gregory finds himself trapped between his idealism and breaking the law – and torn between his two ‘girls’ – one a sexy young schoolgirl, the other a sexy full-blooded woman.
