Lord Wingate, aquitted after appearing in court for fraud, starts up a 'finishing school' to teach girls how to extract money from rich men, in return for a percentage of their gains. He enlists the help of the Duchess of Burwood as a teacher and Hector as fitness instructor. A probation officer friend supplies the first batch of pupils fresh from Holloway prison via a clapped out old mini bus. Suspicious neighbours and police together with newspaper reports naming the prison girls now hobnobbing in high society results in a raid and new court appearance for Lord Wingate. The Judge sentences him but plots to start up his own 'school for sex'.
