Sir Seth and Sir Ollie find themselves in Ah Ah Kaachu, a sleepy place that lives in the shadow of a giant mountain. Elynor, the Faerie Queen of Ah Ah Kaachu, implores the Mighty Knights to help the town. But Sir Seth and Sir Ollie find there's more to be afraid of on this giant mountain than a hairy Yetis. And, as the friends get separated in the wake of an avalanche, their mission becomes a two-pronged race against time, with one knight hurrying to warn the village of the worst avalanche yet, and the other fighting to bring old enemies together to vanquish a newer, and greater, foe.
