Trisha, a lonely unsentimental boozer, unexpectedly inherits a home in the Highlands. She wastes no time leaving Glasgow - and her estranged husband, her insolent teenage son and her boring job. Having pictured a rural idyll, she finds rain, sheep, and kamikaze midges. And more rain. Her only companion is a smelly, brain-damaged dog, but a night of whisky-fuelled high jinks with a frozen salmon leads to a dramatic discovery that will change her future forever, and maybe even her past.
