After Constantine breaks the cardinal Legend rule—you can’t change the past—he, along with Charlie and Zari try to deal with the ramifications without telling the rest of the Legends. Even though Zari encourages them to just fix the problem, Constantine and Charlie are determined to find another way, but only continue to make things worse.

With things getting out of control, Sara and Ava concoct a bold plan to take back the Time Bureau. But when things go awry, Zari and Charlie must work together to discover what Neron is planning. Elsewhere, Constantine is given a tough choice on who to save from Hell.
