Doc Martin: Cats and Sharks

Bert Large's restaurant is in financial trouble - and he is being chased by loan sharks Alastair Tonken and his son. When Ruth gives Al 800 pounds, he uses the money to pay back the some of the loan. But Alastair Tonken tells them they still owe him. Al thinks it is time they stood up for themselves but PC Penhale says he can't help them - it's a civil matter. The Tonkens then put pressure on Mrs Dingley for the money they lent her and Penhale has to break up a fight between them and the Larges. He tells the Tonkens to leave the village and never come back. Eleanor has a plan to help the restaurant in the form of a Spanish theme night. But when she suffers a strangulated hernia, Martin has to operate himself. Convinced that he should resume his career as a surgeon Martin plans to quit Portwenn leaving Louisa and their baby son in the village. There is still the child's christening to organise but as usual the doc shows little interest.
