Louisa faints in front of her class, Aunt Joan nearly runs someone over with her car, and Portwenn’s new policeman is falling asleep on the job.

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.

A family of city slickers moves in next to Louisa, bringing modern ideas about parenting and their bratty son. Doc Martin learns that the constable is agoraphobic as well as narcoleptic.

Romance is in the salty air of Portwenn: Doc Martin is pursued by a glamorous divorcée. Aunt Joan is wooed by a handsome artist 30 years her junior.

Martin and Louisa go on their first proper date. When he ruins a kiss with a tactless remark, it’s the last straw for Louisa.

Dr Martin Ellingham is shocked to find Louisa and Aunt Joan knocking at his door before the Surgery has opened. Louisa has had a medical scare and wants Martin’s reassurance that everything is fine. PC Penhale, still officially the world’s worst policeman, has an unexpected visitor: the older brother he has always idolised, Sam.
