Superman has been blasted on a roller-coaster trip through time by the Linear Man.

Alone, with his memory muddled, he is propelled from the ancient past to the far-flung future and back again. On his unprecedented journey through time, the Man of Steel encounters Nazis, wizards, demons, dinosaurs and three different incarnations of the Legion of Super-Heroes!

Will he ever return to his own time to solve the mystery surrounding his journey? Who is the Linear Man and what is his unknown agenda? And who are the other Linear Men? And how does Waverider fit in?
