Lin Yu, who was watching tigers at the zoo the very last second, ends up being reborn as a two-month-old Northeast tiger cub, appearing in the perilous African savanna. Fortunately, he is mistakenly adopted by a mother leopard who lost her own cubs, becoming the big brother of two little leopards. Facing food-snatching spotted hyenas, swarming African wild dogs, and lion prides that rule the savanna, Lin Yu refuses to follow the solitary path of felines, leading his leopard siblings to start a savanna alliance. Using tactics, Lin Yu subdues the wild dog pack and toys with the hyena pack, turning the savanna's notorious 'gastrointestinal duo' into his younger brothers. Lin Yu proves with his strength that from now on, the African savanna is the Northeast tiger's all-you-can-eat restaurant!
