A village of Yetis in isolation on the top of a mountain in the Himalayas, above the clouds and hidden away from sight. Migo is a yeti who abides by the law of the ancient stones held by the Stonekeeper, the yetis' leader. Migo's father, Dorgle, projects himself through the air each morning to hit a gong with his head, as the yetis believe this wakes up the sun. While learning how to ring the gong, Migo is distracted by the Stonekeeper's daughter, Meechee, whom he has a crush on, and misses the gong, landing outside the village. There, Migo witnesses a plane crash and finds a "smallfoot" (human), whom the yetis believe is mythical. Migo runs back to inform the villagers, but he lacks proof, and Stonekeeper claims he is lying and banishes him from the village. Migo is suddenly visited by rejected yetis Gwangi, Kolka and Fleem who bring him to the Smallfoot Evidentiary Society (aka S.E.S.), which is led by Meechee. She convinces Migo to travel below the clouds despite the stones telling them that there is nothing underneath. After some hesitation, Migo agrees to go, but his rope snaps and Migo falls, where he discovers land.
