An epic cross-era saga, starring both The Tick and The Golden Age Tick! The Tick from Today and The Tick from World War II trade places when The Terror - the only Tick Universe villain old enough to have fought them both! - shoots both heroes with his inter-dimensional-time-travel ray gun! Can the modern Tick cope with the challenges of a wartime comic book reality? And can The Golden Age Tick deal with a world without rationing, big bands and clearly-delineable enemies!
