Meanwhile transvestite David Martin is released once again from prison - he's provocative and aggressive, escaped from prison twice. When he's caught again during a burglary, he shoots one of the police officers. Until 1983 he advances to the most wanted criminal in UK. After a chase through half of London, a suspect is shot by police officer Finn - an innocent, as it turns out, so Finn is suspended.
