Jimmy’s signal watch suddenly summons a genie from another dimension. Jimmy becomes pals with the genie and abandons Superman. When the genie is ready to return to his own dimension, he tells Jimmy he needs radium.

After the radium is found, the genie reveals himself to be Superman in disguise. It was all a hoax to get the crooks to reveal the location of the loot.
