Synopsis:
Using a formula developed by a dead underworld scientist, Killer Shark alters Lady Blackhawk's personality. Zinda is then reconditioned into a criminal by Killer Shark. She assumes the new identity of Queen Killer Shark and battles the Blackhawks. Though the Blackhawks try to restore Zinda to normal, their efforts fail. Killer Shark is captured, but Zinda escapes still under the influence of the formula.
