Arthur is a music salesman with a song in his heart but trouble in his fortunes. On a trip to Gloucester he meets two people who will change his life: a strange 'gentleman of the road ' who plays hymns on a piano accordion and a beautiful young teacher. At home Arthur's wife waits apprehensively.

As Eileen is telling her school children their favourite fairy story, song salesman Arthur, Prince Charming in the tale, is coming back to make her his princess. He finds her in a magical forest. His wife Joan wonders if she has left him for good and the mysterious accordion player still haunts the story.

Arthur has at last returned home to his anxious, waiting wife, who still cares enough to make a new bargain with him. She agrees reluctantly to finance him in his own record shop.

Arthur and Eileen have disappeared. His wife Joan is receiving strange visits from a police inspector, and the case of the murdered blind girl is to be opened.

Arthur is now wanted for murder so he and Eileen are on the run, hungry, desperate, but still together. They hide in a lonely farmhouse, but he makes a fatal error.
