Synopsis:
Jay Garrick and Joan Williams investigate a meteorite landing site. They are soon attacked by a dinosaur and knocked unconscious in a fall. When they recover, they find themselves in a museum and Jay is accused on trying to steal a meteorite specimen.

Jay is taken to jail, but he escapes as the Flash to clear his name. He believes the meteorite samples in the museum are counterfeit, but when he examines them, they are real.

He then follows some museum guards to a collectors house where he discovers many stolen treasures. The museum curator arrives too, but he betrays Flash as he is the real thief.

Flash and Joan are tied up and mummified, but Flash escapes and captures the curator and all his henchmen. With the real thieves in custody, Jay Garrick’s name is cleared.
