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!
