Necrolai attempts to enter a cave, but a magical seal prevents anything evil from entering. She tricks the Rangers into breaking the seal and steals a mummy-like corpse. It is later revived as Imperious, who replaces the fallen Morticon. Meanwhile, the Rangers have obtained from the cave a lamp containing Jenji the Cat Genie (to whom the title refers). The Rangers try to get some wishes from the tricky Jenji, but they will need all the help they can get when they face Imperious.
