Lack of funds force Trisha, an unsentimental lonely boozer, to return to her previous profession as a pharmaceutical rep, pouring tea and telling jokes to sad burnt-out GPs. The only good news is that Steven, her increasingly distant teenage son, is about to move back in with her. The bad news is that Bob, her ex-husband, wants the house.

Trisha's mind is unexpectedly made up when she inherits a place in the Highlands. Having pictured a rural idyll, she finds rain, sheep, a jaywalking dog and kamikaze midges. And more rain. Her social life is so limited that she even contemplates joining the Inversnechty Mental Health Awareness Group just for the craic.

Then three nurses on holiday leave from Saudi invite Trisha to a ceilidh. A night of whisky-fuelled high jinks with a frozen salmon ensues which leads to a significant encounter with Spider, the local Lothario, and a dramatic discovery that will change Trisha's future forever.
