In the snow-capped valley, the lovely Poluru and Petty, Eddie, Cologne and other friends are playing sleigh games. They admire the White Tigers who have won the Northpian Super Sled Race and hope to participate in the race one day. Smart Eddie invented a new sleigh, and Polulu boarded it, but the sleigh was so powerful that it flew out of control into the sky and nearly ran into the delivery plane of express champion Taobao and Mango. When Taobao failed to dodge and forced to land in the valley, Polulu blindly regarded him as the sled master of the White Tigers and asked Taobao to be their coach. A few days later, when the plane was repaired, the kids quietly followed the plane and went to Norspia, which they had been looking forward to for a long time. The grand competition is about to begin, but the evil forces led by the gangster Fire Bear are also creeping closer to Norspia.
