Cath Hardacre is a hardworking and skilled nurse who loses her job for whistle-blowing and is forced to take drastic measures to provide for her daughter. Out of desperation, Cath seizes the opportunity to steal her best friend's identity as a senior doctor and start a new life in Edinburgh. Burying herself deeper and deeper in the imposter persona, she realises she could get everything she ever wanted - but with her old life threatening to destroy her fragile creation, how far will she go to protect it?

Set around the antics of a ragtag group of Mountain Rescue volunteers, Mountain Goats celebrates the Highlands of Scotland, with proper kilt wearing maniacs fighting disaster on a weekly basis against the stunning backdrop of the Glencoe hills. When our heroes aren't out rescuing people, or being rescued themselves, they spend their time in 'The Old Goat' pub - a place of great warmth and camaraderie, where people come in for a quick pint and never want to leave. The regulars in the pub are Jimmy, an old school mountain goat with a fag burn in his jumper and a glint of mischief in his bloodshot eyes, the wild and mysterious Bill; Bernie, a cheery, hard-working woman, who keeps the others on the straight and narrow; and Conor, a handsome, easy-going young man who is more than a little bit naive. Their HQ is in the local pub, and the landlady is Jules - a formidable force of nature who'll have you out on your ear at the first sign of trouble.
