Doc Martin S04E01 - Better the Devil

Since calling off his marriage to Louisa, Martin has begun to question what keeps him in Cornwall and realises that if he is ever to escape, he must conquer the blood phobia that ended his surgical career. Encouraged by aunt Joan's friend Barbara he tackles his fear, but after an accident the pair end up in hospital, where he bumps into his girlfriend from medical school. Later, the return of a familiar face shakes him up even more.
