   Summary

   After a catastrophic accident, Barry Allen—the Flash—finds himself transported further back in time than ever before, inhabiting the body of his younger self, Sebastian Smythe. Now reliving a different life with new challenges and relationships, Barry must protect his secret, safeguard those he loves, and confront old enemies. As he grapples with the impact of his actions on past and future events, Barry faces the ultimate question: can he truly change fate or will history simply repeat itself?
