April is covering the revival of the luxury train the Orient Express. Shredder is on the train with Rocksteady and Bebop carrying the Supercharger, a device to accelerate the train to superspeed, sending it out over the Bosphorus and crashing into the Middle East oil fields, destroying them. The Turtles board the train and send the Supercharger flying with Shredder aboard.

A descendant of the Viking raiders, Eric Red, seizes both April and Professor Swenson's map to the underground volcanos in Scandinavia. He plans to tap into the molten energy, melt the polar ice cap and flood the world's coastal cities, making them easy prey for his wanna-be Vikings.
