Brian Davis had a successful career in advertising journalism once; the documentary begins with him homeless in London, drunk and asking mates for money so that he can go to Paris to interview Roman Polanski.

He scored 150 quid and literally ran to the Turk’s Head in Soho to drink it all. So much for Paris.
