At the tomb of King Nutun-Khamun, an archaeologist known as Dr. Crockery finds the ring to unlock the diamonds of the Sphinx of Inka-dinka-do. His greedy assistant Wexler steals the ring and eludes the mummy assigned to guard it, Hiram. Wexler tries to hide the ring and Dale gets it for a while, putting the Rangers on the case.
