"Meet Martin Ellingham, an eminent physician with a nasty disposition. Forced to give up his career as a London surgeon after developing a fear of blood, he takes a job as GP in the sleepy Cornish village of Portwenn. His irascible manner and permanent scowl soon have the town in an uproar; he insults each patient he sees and offends nearly everyone else. The only person who's glad to see him is his aunt Joan."--Sleeve. Episode 1. Meet Martin Ellingham,...

In the sixth series, the doctor tackles fatherhood and his complicated relationship with local teacher Louisa.

The first annual Portwenn charity fun run leads to a rivalry between Bert Large's restaurant and a local pub. Louisa's mother, Eleanor, shows up unannounced, and while Louisa isn't happy to see her, the baby starts sleeping more soundly under Eleanor's care.

Doc Martin's return to London is delayed by the birth of his son, the arrival of an incompetent replacement at his Portwenn practice, and the sad news of a sudden death. He temporarily moves in with Louisa and their still unnamed baby.

The annual Portwenn Players Dance is a highlight of the village's social calendar. Louisa invites Martin, but the doctor turns her down. Martin also pays a visit to a park ranger who believes he lives with a six-foot squirrel.

(Aired in the US as "Movement") Taking Doc Martin's advice to "make some life changes," Bert Large abandons plumbing and opens a restaurant. Soon Portwenn is plagued by an outbreak of food poisoning.

An accident in the local fish-and-chips shop and a nasty skin rash at the school make Martin even crankier. Louisa is up for headmistress, and Martin, as an unwilling governor of the school, must decide if she's in or out.

There's something wrong with PC Penhale's older brother, Sam. Elsewhere, Bert Large gives romantic advice to his son, Al, which only makes things worse with Pauline.

With Janice's departure, Martin and Louisa need to find a day care for James, and they settle on Portwenn Tots. Ruth considers selling her farm, and Mrs. Tishell's pharmacy receives a new blood-pressure monitor.

Ruth has a mystery admirer who unnerves her. Louisa becomes Bert's least favorite person when one of her pupils pens a damning review of his restaurant in the school magazine.
