Looten Plunder leads a whaling operation with Dr. Blight aboard attempting to concoct the perfect poison, and the Planeteers are enraged to see that it is legal for him to kill whales with calves - as the Japanese whaler Masuyo would rather not do - simply because he claims that he is "experimenting whale-repellent". Masuyo's son Tykoshi fails to plead with his father not to hunt so resorts to stowing on the Whale-B-Gone ship, but is accidentally knocked overboard by one of Blight's beakers, and rescued by the Planeteers. They join forces to try and find evidence that they are actually illegally whaling for profit, but are under attack from harpoons, traps, and poisons to prevent any help Captain Planet may give them.
