The Turtles - along with their brother, the neo-vampire Raphael, as their prisoner - and the time mistress Renet plunge in pursuit of Savanti Romero and his monster horde - Dracula, Frankenstein, Vulko the werewolf and the Mummy - through a time tunnel back to the place where her journey began: New York City in the 21st Century, shortly after the onset of the monster plague and just before her ensuing escape back to Ancient Egypt, which can be followed from a nearby roof.

Raphael, still a loyal servant of Dracula, taunts his brothers and summons reinforcements from the ranks of monsters below them. Forced by the growing power to flee, the Turtles and Renet go down to the street as fast as they can and flee back into the sewers, using all their skills. There, they begin to desperately search for ideas on how to defeat Savanti's monsters and undo the monster plague; but unfortunately Raphael manages to hypnotize Michelangelo and make him take off his shackles. Raphael immediately sneaks into Donatello's lab and grabs the Time Scepter which should just be recharged.

Meanwhile, at his new headquarters, Saint Patrick's Cathedral, Savanti Romero fears that Renet and the Turtles may still throw a wrench into the gears of his plan to transform all mankind into monsters like himself. To track them down, Dracula calls his vampire slaves April and Casey, and using their information, Savanti sends them, Frankenstein's creature and a monster army to the hideout of the Turtles, just after Raphael was able to break free. During the ensuing battle, Donatello is bitten by April; this and the surprise element force the Turtles and Renet to escape again. They entrench themselves in the sub-hall operating room of a derelict hospital, but there the vampire germ completely takes possession of Donatello and turns him into a neo-vampire as well. Now only three of them, Leonardo, Michelangelo and Renet flee back to the surface.

But in the meantime there are tensions between the top monsters Savanti and Dracula. Dracula, who Savanti's plans did not match his right from the beginning, is given the Time Scepter by Raphael, but can not activate the artifact himself to the mockery of Savanti. Now that the vampire lord has shown his true colors, Savanti sics the Mummy on Dracula, but he destroys it with his own powers with only one stroke. Now that they are in a stalemate, the two are forced to continue working together against their common enemy, catching the three fugitives as they emerge from the sewer system in Chinatown. Michelangelo makes one last attempt to draw Frankenstein back to thier side; a desperate move that happily succeeds, with Frankenstein's strength as support, the tide is now beginning to turn in favor of the protagonists.

Savanti and Dracula decide to use the Time Scepter together against their opponents; Michelangelo snatches the rod from them, but doing so accidentally damages the scepter, triggering a time-travel effect that puts all the main participants in the Cretaceous period after a few random stops. There, Dracula attacks the Turtles, while Savanti hastily tries to repair the scepter; but Michelangelo drives Donatello's staff with the magical seal of protection through the heart of Dracula and destroys the vampire. Savanti is about to use the Time Scepter against them, but is knocked down by Renet, who snatches the Scepter and the emergency time module and opens a time gate back to the present, while Savanti remains stranded in prehistoric times, and is promptly chosen as breakfast by a tyrannosaurus.

With the destruction of Dracula and the recapture of the Scepter, the curse is taken from the New Yorkers, and all the victims are restored to their original state. After the friends have enjoyed a moment of victory, Renet brings Vulko back to the past and to his daughter, while Frankenstein is to have a new home in the, far more tolerant future. With a kiss for Michelangelo and the promise to see her again in the future, Renet says goodbye to her turtle friends, and the Turtles decide to celebrate their victory by resuming their Halloween tour.


  • The word "Zounderkite", which Dracula uses in English in reference to Savanti Romero, is an outdated form used for the term "Idiot" or "Klutz", which supposedly dates back to Victorian times.
