As part of his latest plan, Krang brings General Traag to Earth from Dimension X as a distraction for the Turtles, while Krang tries to turn a laser at the ice and free the Technodrome from its prison at the North Pole. Meanwhile, Donatello learns a new fighting move, Wu Wei, where one ninja turns his opponent's attack against him without action.

Irma gets super magnetic powers and starts to fight crime. She decides to stop Krang's plan. When her powers wear off, the Turtles foil Krang and rescue Irma.
