Kaa visits Baloo with an urgent message. Thuu, the white cobra, has gone missing. Since Thuu normally guards the Treasure of Cold Lair, there's now a risk that it will be discovered by humans. Mowgli befriends a female monkey called Langur who has seen men with guns at the Cold Lair. Baloo, Bagheera, Mowgli and Langur try to guard the treasure and ward off the humans, but Baloo is injured so Shere Khan is reluctantly recruited to help drive the humans away. However, this cunning tiger can't be trusted.
