Teenage superheroes strive to prove themselves as members of the Justice League.
Bruce Wayne is missing. Alfred covers for him while Nightwing and Robin patrol Gotham City in his stead and a new player, Batwoman, investigates Batman's disappearance.
After discovering he has powers, 11-year-old Jonathan Kent and assassin-turned-Boy-Wonder Damian Wayne must join forces to rescue their fathers (Superman & Batman) and save the planet from the malevolent alien force known as Starro.
