An embezzler and his daughter crash their plane in the jungles of Africa. Young Doreen (Julie London) is the sole survivor and befriends a gorilla, Samson, who becomes her guardian. Ray Gorman (Buster Crabbe) is out to clear the name of his father, who isfalsely accused of stealing the money. Ray is unaware that he is being trailed in the jungle by scheming couple Carl and Marie (Barton MacLane and Fifi D'Orsay) intent on stealing the treasure that is guarded by a White Witch and her ape companion. The parties clash in double-crossing treachery that unleashes the fury of Samson. Nabonga borrows from King Kong and the "gorilla gone wild" pictures of the era and is a classic tale of beauty and the beast.
