Nature documentary about a young wildebeest in the wilderness of Africa. The gnu calf strays from the herd and comes upon a lioness that kidnaps it. Instinctively, it treats the lion like its mother. And miraculously enough, the lioness does not see the calf as its prey. Like a true Survivor, the calf manages to escape from the lion's den and find its way back to its real mother.
