The Lord of Time has set a plan in motion that even he is unable to stop. In mere hours, his computer will stop all time... a good idea, he once thought. But upon further study, he learned that once stopped, time could not be restarted. Desperate to prevent his own plan from coming to fruition, but unable to stop it himself, he relies on those who have foiled him time and time again... the Justice League and Justice Society. But he judges that even these heroes won't be able to succeed. In order to strengthen their spirit, he must first hand them their first true defeat.
