Passenger to London is a murky spy thriller, made in Britain and lasting just an hour in length. There are no famous actors in it so it has a very low rent feel. The story sees a secret agent sending a secret message on a train journey before being murdered. His contacts in London then have to figure out the meaning of his message and also try to solve his murder at the same time. This film's the definition of a potboiler, shot at speed on the cheap and with a very familiar storyline. However, it also features enough incident and sinister characters lurking around to hold your interest throughout.
