A Tale of Africa (1980)

An old man (Jimmy Stewart) has settled in Kenya, in a remote cabin, with his adult granddaughter and several of her "animal friends". They live an idyllic life amongst the wildlife, unseen by all except a tribe of nomads, with whom they trade. But when a plane crashes in the nearby forest and its lone passenger is left an amnesiac, he stumbles into their lives and sets in motion a chain of unexpected events.
