Synopsis:
On the trail of criminals, the Titans run afoul of the Hawk and the Dove, who are after the same gang for different reasons. After a brief altercation, Wonder Girl accompanies Hawk and Dove through a teleportation device to a gang hideout in Istanbul, while Robin, Kid Flash, and Speedy battle another segment of the organization in Berlin. Both teams are defeated and captured, but Hawk, Dove, and Wonder Girl escape in time to rescue Speedy from being crushed beneath a gigantic machine. Hawk and Dove, sensing their mystic transformation back into Hank and Don Hall about to occur, are forced to abandon the case, leaving Speedy and Wonder Girl to search for Robin and Kid Flash, who are still prisoners of the Dimension X aliens.
