With the re-emergence of Doctor Light, the old Titans reluctantly return to the Titans tower to strategise against their old enemy. But the secrets of the Titans' past threaten to tear apart this newly formed team from within.
Five years ago, the Titans and Garth aka Aqualad are growing into a tight-knit family. But their personal feelings start to bleed into their work, and with the arrival of a new villain, they begin to question their destiny as heroes.
With the team in disarray, Dick and the others vow to do everything in their power to save Jason's life. Gar's guilt over Jason's kidnapping complicates the mission, while Rachel's dark secret continues to gnaw at her.
As Dick sets out alone to track down Deathstroke, a familiar voice begins to haunt him - taunting him and attempting to guide him back to being the leader the Titans need.
After the murder of Aqualad, Dick, Donna, Dawn and Hank befriend Jericho Wilson, Deathstroke's son. Realizing that Slade's devotion to his son might be Deathstroke's only weakness, Dick is eager to use the information against his nemesis.
Dick's confession causes the Titans to go their separate ways. Hank and Dawn try to start a new life. Koriand'r encounters an unexpected threat. Gar tries to help Conner adjust.
While Hank is busy cage fighting after breaking up with Dawn, someone steals the Hawk suit. Donna and Dawn finds a way to rescue Gar from Cadmus facility. Rose reveals her secret to Jason. Dick escapes from prison to find Jericho.
