When teenage girl Yi (voice in the original: Chloe Bennet) meets a scared yeti on the roof of her flat in Shanghai, she can hardly believe her eyes. After gaining the trust of the magical creature, she baptizes him in the name of Everest. After all, that is also the home of the creature – and that’s exactly where she wants to go back. Together with their friends Jin (Tenzing Norgay Trainor) and Peng (Albert Tsai), Yi and Everest embark on an adventurous journey across China to reunite their new companion with his family. Among others, they have to deal with the stinking laboratory head Burnish (Eddie Izzard) and the zoologist Dr. Ing. Kill Zara (Sarah Paulson). Because they are after the mythical creature, to abuse its ability to influence nature, for their own purpose.
