Plot Synopsis
Hokum Hare discovers that The Shredder is using a time train to travel to the future and become a crime lord in an era without crimes. Shredder originally proposes to travel to the year 3000, long after the TMNT have died so that he won't have any TMNT to encounter and destroy. However, Krang makes an error in the programming of the time portal, located in a subway tunnel, and when Shredder and the mutants pass through the portal, they end up only in the year 2036. The Turtles and Hokum jump on the time train. When they arrive in the future they find the elder versions of the turtles, who are retired. Now, the younger Turtles try to whip their older selves into shape before the big confrontation.
