The story revolves around Deathstroke trying to steal the Flashes' powers to travel back in time to save his son.
In the current day, Slade wakes up in the hospital after his beating from Jericho with his friend Billy Wintergreen by his side.
Damian insults and criticizes Kid Flash for trusting Deathstroke, and starts to lose his speed.
The two teams try to find Deathstroke, leaving Kid Flash and Aqualad behind (with Raven criticizing Damian's behavior).
Wintergreen gives Wallace and Aqualad a ride, while Deathstroke successfully travels to the past and sees his son again.
Damian uses a palm technique called Commoto Cordis on past Wally West to make his heart stop.
Deathstroke arrives in the present and plans to go into the Speed Force to go even farther back in time, and after he is done he will kill everyone.
Everyone is okay with this outcome, except for Kid Flash, who says that they're acting like Deathstroke, and goes back in the Speed force to save Slade.
Nightwing tells Omen to create a psychic link with Raven, and Raven will use her powers to astrally project into Jericho, and Jericho will use his powers to transfer his conscious into Wally, which will create a near communication field (that links the Teen Titans and Titans with the exception of Damian) that will give Wally extra speed.
In the epilogue, Damian fires Kid Flash because he trusted Deathstroke and nearly put innocent lives at risk.
Wally learns that due to Damian nearly killing his past self, his heart needs to have a pacemaker and he can't run as fast anymore.
Deathstroke decides to create his own version of Teen Titans that includes Wintergreen, Jericho, and Rose Wilson.
