A discovery from TMDB

Box for One

A London "spiv" enters an outdoor telephone booth. He dials a number and asks if there's a message for him. As he goes to leave, the phone rings - it is a girl who is trying to find her boyfriend and has the wrong number. The spiv is on the run from gangsters and is looking for help. He tries various people but they reject him. Eventually the gangsters catch up with him.
