Doc Martin treats an uncomfortable Louisa Glasson for suspected anaemia, and a reluctant Aunt Joan is forced to receive treatment from Martin.

When Bert Large hosts an opening night for his new restaurant, Doc Martin is busy treating a host of patients with suspected food poisoning the next day.

Aunt Joan begins a relationship with someone much younger after finding out she has osteoporosis; glamorous divorcee Carrie Wilson angers Louisa by going after Dr Martin.

Louisa finds her new neighbours irritating. Meanwhile, Martin and Louisa find their romantic meal ruined by Anthony and Terri Oakwood's sudden arrival.

Martin thinks PC Penhale's much loved brother, Sam, has a rare genetic disease, but instead his findings change PC Penhale's opinion of Sam forever.

While on a first date with Martin, Louisa seizes the opportunity for a kiss. Later, Martin proposes to her.
