The comedian ventures to the islands of Mull and Staffa, nestled along the west coast of Scotland and home to some of the most breathtaking sights the country has to offer. Beginning her trip in Staffa, Susan visits the cathedral-like cavern of Fingal's Cave, one of the UK's true natural wonders formed over thousands of years. Her need for speed is fulfilled when she witnesses the Mull Rally, while in Tobermory, she visits a biscuit factory run on sustainable energy. Lastly, the presenter goes in search of the largest bird of prey in the UK - the white-tailed sea eagle.
