Leo and Tig set off on a journey to faraway Lake Baikal to bring back home the lost seal pup named Lufi. Along the way, they make new friends with Zhu, a red panda, and Wukong the Monkey King. They also cross paths with the evil chieftain of a horse herd Tengri-Khan, who wants to seize the seal. For whoever brings Lufi home will be granted any wish by the Master of Baikal – the great dragon Lusud.
