After learning that his wife has been cheating on him with all three of his best mates, Doctor Martin Bamford impetuously leaves London for a week in a coastal village he visited as a child. Charmed by the scenery and the locals, he stays longer than he planned and helps solve a mystery. [NB: When picked up by ITV, the character's name was changed to Ellingham, and his personality made more socially inept, a 'townie' uncomfortable with the countryside]
