Having been sent a picture of her husband, a war hero killed in France, Meg Elgin is led to believe he is still alive and arranges a meeting at a London railway station. When she arrives there with the police accompanying her, she catches sight of a man in the distance wearing an old coat of her husband's. When he is pursued and captured, he turns out to be Duds Morrison, a former soldier and out-of-work actor recently let out of prison. He refuses to tell them anything, and having nothing they can charge him with, the police release him. His interest aroused by the pictures sent to Meg, her new fiancé Geoffrey Leavitt follows Morrison and tries to demand an answer from him about his sudden appearance masquerading as Meg’s dead husband. Morrison again refuses to talk, and tries to flee from Leavitt - into an alley where he is set upon by a gang of ex-soldiers who beat him to death and take Leavitt off as a prisoner. It is soon revealed that they are ex-commandos, and former comrades of Morrison, with whom they served on a raid in Brittany in the Second World War. The commander of the raid had been Meg's husband, Major Elgin. The men had been led to believe that Elgin secreted a large amount of treasure in a house in Brittany. Now that he is dead they are desperate to get their hands on it. They are wary of their former sergeant, a psychopath named Jack Havoc, who has recently escaped from prison, committed several murders, and is also seeking out the treasure. They had attacked Morrison because they believed he was an accomplice of Havoc. Wearing their old uniforms they have spent the past few years trying to carve out a living as street musicians, begging from passers by. Realising that releasing Leavitt might open them to being charged for the murder of Morrison, they bind him up and keep him as a prisoner. He is rescued later by a beat constable who investigates the squat while the musicians are out. Leavitt returns to Meg and together they head to Brittany to find the treasure. Havoc, now united with his former comrades, also travels to France where he discovers to his disgust that when Major Elgin had spoken of his ‘priceless’ treasure, he had in fact been referring to its artistic beauty rather than its monetary worth. The treasure is in fact a statue of the Madonna.
