動物園裡, 母虎產下三隻小虎後失救致死, 園方請來溫馴的母猩猩充當褓母, 在她悉心照料下, 幼崽茁壯成長。可是戰火忽然爆發, 動物園淪為廢墟, 為求生存, 母猩猩被迫帶領小虎重返野外, 展開一場殘酷淒美的蠻荒之旅。Three Tiger Cubs, One Accidental Mother, An Unbreakable Bound. Three Cubs nestled safe in the zoo, cared for by gorilla and man. But when flames of war reach their home, they are thrust alone into a savage wilderness. Here, family bonds will be tested in a land where courage means survival. Their exodus is a trial of fire, and only the bold of heart will endure to see if home is more than fading memory.
