This story features Superman and his son dealing with a rogue Tim Drake from an alternate future.
Damian wakes up and finds Superboy and drives him somewhere safe, while Tim Drake regains consciousness and calls himself Savior.
Savior finds the Teen Titans regain consciousness and tries to convince them that he needs to kill Jon Kent and anyone who stands in their way.
Aqualad finds Superboy since he gives off an energy signature and the rest of the Teen Titans manage to convince Damian and Jon Kent that they're not going to hurt them.
They all go to the Fortress of Solitude, where Jon finds his dad in the Red Kryptonite cage and frees him by using his solar flare.
Beast Boy and Raven try to contain the blast while Bart and Wallace run around in the opposite direction to reverse polarity.
Superman and Conner Kent decide to go into the solar flare to save Jon, but Savior realizes that the containment isn't working and he decides to absorb the solar flare all by himself which saves Jon but pulls Savior back in the timestream with him vowing to fight anyone who interferes in it.
Wallace and Bart decide to use the Speed Force to send the Titans of Tomorrow back to their respective time.

It's too soon to tell if the rest of the crossover will live up this opening chapter, but it's a great calling card for Jimenez's future work.
