Synopsis:
Superman finds a jewel in space and gives it to Perry White. He then leaves on another space mission for several days. Perry accidently breaks the jewel into three pieces. He gives a piece to Lois and one to Jimmy.

That night Jimmy and Perry are taken over by aliens using the jewels to take over Earth minds while they sleep. Lois did not sleep that night, so she is not taken over. She learns of the alien plan and avoids sleeping until Superman returns. The aliens try and get Lois to go to sleep, and after several days they finally succeed. However, Superman arrives in time to destroy the jewels and stop the alien plan.
