Derek Farr plays Brown, an Army deserter, who is hiding out in a seaside pub but when one of his old Army comrades (Kenneth More) recognises him and tries to blackmail him he flees to London.
Penniless and in danger of being thrown out on the street he mistakenly gets involved in an armed robbery and accused of murdering a policeman. While on the (literal) run from the law he barges into the home of Jean (Joan Hopkins). Jean believes him but the police are hot on his trail. His only course of action is to find the real villains and clear his name...
A nicely tight and gripping noir. Post-war bitterness is very evident, Farr gives his reasons about why he deserted and how badly the Army treated him. Tension between soldiers and civilians they think didn't pull their weight in the war is also portrayed.
