The Mountain (2015)

The funicular train comes off its tracks. Ruari the ski patroller turns gamekeeper.

Spud the piper returns and gets a riding lesson, Ruari goes diving for his wedding menu, the oldest ski tow on the mountain needs demolishing, and a young mountain biker gets out of school to go racing.

This time: the steam railway gets a little overheated, the mountain team battles the midges, the dreams of Rona the downhill racer come adrift, and the pub springs a leak. Disaster all round really.

The mountain team has to call in the helicopter to reach their remotest ski tow, the Glorious Twelfth looks less than glorious, Ruari goes up the creek on his way to his wedding, and 25,000 people turn up in Aviemore to hear Spud the piper.

Perhaps the UK's weirdest music festival gets under way, the sailing school calls up new management to survive, and the ski patrol team takes on the adventure triathalon.

As the summer comes to a close with a big splash, the mountain gets its new ski tow installed in the nick of time, and Polly and Ross count the cost of a busy summer.
