The FLASH is seeing double . . . or triple! Three crooks, mirror images of one another, are robbing CENTRAL CITY. And when the SCARLET SPEEDSTER chases them, they disappear into a shiny storefront window without crashing. There's only one thing left to do: FLASH has to zoom through the looking glass himself. On the other side, he doesn't believe his eyes. He finds a dazzling kingdom ruled by the mesmerizing menace of the MIRROR MASTER ! If the super hero can't fight off his foe's hypnotic tricks, it will be lights out for the FASTEST MAN ALIVE!
