01PLOT

During his meditation, Splinter is contacted by his old mentor Mogo-san, who reveals that he is visiting New York and asks his old pupil to meet him. Splinter is somewhat anxious about leaving the lair, but he goes nonetheless.

Meanwhile, April O'Neil covers a gang of criminal ninja who have been terrorizing the city, the Black Heart Gang, led by a man named Yoku. Shredder and Krang watch the report, and decide that they should get the strange ninjas to work for them.

Mogo is rather shocked when he sees that Hamato Yoshi has become a giant rat, but he soon reveals why he's in New York. He is bringing the sacred white belt of the Mogo clan, to pass it on to his grandson Yoku. Splinter believes that the Turtles can help locate his sensei's grandson. After the Turtles are introduced to Mogo, Donatello reluctantly reveals that Yoku has become a criminal.

That evening, Yoku leads a raid on a jewelry store, while Shredder watches with great interest. He approaches the ninja gang and easily trounces them, offering them Dimension X weapons in exchange for secret government plans.

The Turtles apprehend Yoku and bring him back to the sewers, where Mogo chastises him and gives Splinter the white belt, ordering him to burn it rather than let it be dishonored. Yoku then escapes. April is captured and used to infiltrate a government facility Shredder wants breached.

When investigating a restaurant the Black Heart Gang frequents, Michelangelo uncovers a basement where April is held captive. It is revealed that the bank president Mr. Crocker is the Gang's secret boss, but just as the Gang is about to kill the Turtles, Yoku turns on them. The maps given to Shredder turn out to be fakes.

After the Gang and Crocker are apprehended, Yoku reveals he is actually a government agent who infiltrated the Black Heart Gang. He reaches his grandfather just before he sails back to Japan. Mogo regrets asking Splinter to burn the belt, but Splinter reveals he never did, knowing deep down that Yoku was honorable.
