Plot Synopsis

While the Turtles are looking for more of Splinter's data-bits in cyberspace, the Cyber Shredder unleashes a powerful virus that wipes the Turtles memories and turns them into mindless drones of the Foot. April, Casey and Serling must then reach them in time before its too late by causing favorite memories of each Turtle to be remembered.
