Issue 1 synopsis:
The story opens at Bruce Wayne’s 75th birthday party, as he is brutally murdered by an unknown assailant. The current heroes of the time, the Justice Titans, who are actually the children of the old guard, are finishing up on a recent mission. However, three of their number stayed behind at their HQ just in case something came up. They don’t stand a chance. Tempest, daughter of the late third Aquaman, Red Arrow, daughter of the late Roy Harper, and Darkstar, son of the late Donna Troy, are martyrs for the first serious mystery this team has had to encounter. There is only one active hero remaining of the old guard, and protecting him may prove to be more of a hassle than they had wished for!
