As we reach the final episode in Series 7, Martin finds himself in a very unusual situation: trapped by Annie Winton, who desperately wants him to try and save her husband, Jim Winton, despite Jim having been recently diagnosed with terminal cancer. Annie insists that there must be something that Martin can do to help. Meanwhile, Ruth and Bert have a proposition to put to Al, regarding the whisky and the B&B. Louisa is very worried about Martin, and wonders if the breakdown of their therapy could have led him to decide to leave Portwenn for good. She calls on Morwenna, Janice and Ruth for help, but none of them have seen Martin. Penhale drives Louisa up to the Winton Farm, where despite Annie trying to persuade them otherwise, they discover Martin. Now reunited with Louisa, Martin manages to eventually find Jim and perform a life saving operation on him. But is it too late for Martin and Louisa to also save their marriage?
