In Aurora Village in the high frozen peaks of the mountians, it's getting warmer, and the snow is melting. The Snow Hams that live there believe that Bijou is their Snow White Princess who can pray for the snow to come back. They send Crystal the snow fairy hamster to summon Bijou to their land.
Crystal arrives and takes Bijou back to Aurora Village, the Ham-Hams quickly tag along. Meanwhile, pirate hamsters are sailing above the village in their flying pirate ship. The captain of the ship, Hamstern, kidnaps Bijou because he doesn't want her to pray for the snow. Hamtaro and his friends board the ship and refuse to leave without Bijou. Hamstern challenges Hamtaro for Bijou's freedom.
Now Hamstern and Hamtaro must compete each other in the Grand Prix, where they race in all sorts of ways. If Hamstern wins, he gets to keep Bijou on his ship. If Hamtaro wins, Bijou can pray for the snow and go back to her friends.
