Donatello is interested in astronomy and uses his knowledge about where Jupiter was in 1909 to learn it's present location, 80 years later. The other turtles interrupt him and when Donatello believes it is the Shredder but it is the turtles who have no more pizza.

Dressed in human disguises, Donatello and Raphael go to the supermarket store to buy some pizzas. It is late in the evening. They have a feeling that they are followed. On their way back, they try to take a shortcut but meet a gang of young street punks who try to rob Donatello and Raphael on their money. Donatello and Raphael take off their clothes to show they are turtles. Suddenly, a young boy wearing a turtle costume, and who calls himself Zach "Master Ninja Turtle and the Scourge of Evil Doers," appears. Zach is equipped with an ice hockey stick as weapon. Zach tries to attack the street punks, but falls to the ground and Donatello kicks a dustbin towards the street punks. A fight erupts between the turtles and the street punks, and the street punks soon run away. Zach tells the turtles that he has got some information about them, and now he wants to help them fight crimes.

Donatello and Raphael tell Zach that he shall go home before he comes in trouble. Zack leaves them, but first he picks up Raphael's Turtle Com, that Raphael lost in the fight against the street punks. Raphael's learns that he lost his Turtle Com.

Meanwhile, inside the Technodrome down below the city, Krang tells Shredder, Bebop and Rocksteady that within 24 hours there will be a rare planetary conjunction, involving the Earth, the Moon, the Sun and Mars. Shredder, Bebop and Rocksteady take a transport module to the surface to steal some "Capsidium Crystals" at Marconi Labs and place them under the telescope inside the planetarium. When the Sunlight from the planetary conjunction hits the Capsidium Crystals, it will create enough energy to re-power the Technodrome and raise it to the Earth's surface.

When Zach comes home, his bigger brother doesn't believe Zach when he said that he find the turtles.

Later that night at Channel 6, April O'Neil and Irma gets information about a break-in at Marconi Labs. Two thieves are described as looking like a rhino and a warthog. That can only mean two Bebop and Rocksteady. April contacts the Turtles via her Turtle Com and they say they will come. Zach, who has Raphael's Turtle com without Raphael's knowledge about it, gets the same information as the turtles, and tells April that he will come.

At Marconi Labs, Bebop and Rocksteady steal the Capsidium Crystals when the turtles and April arrive. Zach arrives on his bike but falls into a pit in the center of the room. This gives Shredder the opportunity to escape with the stolen Capsidium Crystals. But first, Shredder pushes a bottom in the lab which starts a swinging pendulum, so the turtles have to save Zack from being crushed. Bebop and Rocksteady make things wore by standing and fire at the turtles with their guns. Raphael saves Zach, and Shredder, Bebop and Rocksteady escape. But Rocksteady tells April that tomorrow, they will raise the Technodrome.

Zach tells the turtles that his name is Zach, and that he soon will turn 14 years. After a short discussion, Zach disappears and Raphael realizes that Zach has Raphael's turtle com, so Zach could know that the turtles were at Marconi Labs.

The turtles return home to their New York City sewer lair in the Turtle Van, not knowing Zach follow them on his bike. When the Turtle Van parks, Zach uses a trick to follow the tracks turtles.

Back in the Technodrome, Krang blames Bebop and Rocksteady for the mistake because telled about their plan.

In the sewers, the turtles and Splinter talk about what Rocksteady said about the Technodrome. Donatello say that during tomorrow's conjunction, Shredder can raise the Technodrome.

Suddenly, Zach arrives and tell them that he used his equipment to find them. Zach is welcomed by Splinter for, even if he is young, doing something that many older and wiser people tried but never did: finding the turtle's sewer lair. He shows Raphael's Turtle Com, and shows a sound-trick with it by using a microphone.

In exchange for promising not to interfere the turtles anymore, the turtles give Zach a tour in the their lair.

Meanwhile, Shredder, Bebop and Rocksteady hide in a basement and watch a video about the incidents at Marconi Labs. The videotape shows Zach on his bike, and Shredder calls the police and tell that he found a bike he wants to give back to the owner, and he tells the number. The police give Shredder Zach's address, and write it down. He then sends Bebop and Rocksteady to go home to Zach and kidnap him.

Bebop and Rocksteady arrives at Zach by climbing up a ladder. Zach sleeps, but awakes when he hears something outside. He sees it is Bebop and Rocksteady, and hides in a wardrobe, so they can't find him. But Bebop mentions the word planetarium before he and Rocksteady go away.

When Krang hears that Bebop and Rocksteady failed to capture Zach, he tells Shredder that he will send some Foot robots instead.

Donatello learns that Shredder can use the planetarium across from the City Park in his plans.

Shredder, Bebop and Rocksteady arrive at the planetarium. Zach also arrives on his bike, and he believe Donatello is smart enough to learn that Shredder needs the planetarium. Rocksteady captures Zach.

The turtles arrive in the Turtle Van. Donatello and Raphael fight the Foot robots while Leonardo and Michaelangelo go inside the planetarium.

Shredder shows Leonardo and Michaelangelo that Zach is captured, and forces the two turtles to give up.

Outside, Donatello and Raphael manage to send the Foot robots, who are firing laser, down to the Technodrome in the transport module. Donatello and Raphael go inside the planetarium, but is captured by Shredder. Shredder has tied all the turtles and Zack to chairs. The planets are aligned as Krang drives the Technodrome towards the surface.

Donatello says that the Capsidium Crystals are sensitive to sound. Zack uses his Turtle Com-sound trick with Donatello's Turtle Com, and the planetarium echoes with an ear-piercing sound that shatters the crystals. The Technodrome to falls back toward the center of the Earth.

The turtles use a broken crystal shard to cut themselves and Zach free from their ropes and go after Shredder, Bebop and Rocksteady, who escape. Shredder throws a smoke grenade to cover their escape. Then they see that the transport module is gone, they jump down in the hole and fall down all the way back to the Technodrome.

Back at the turtles' sewer lair, Zach is given his own Turtle Com, and they tell him that he can always come to them. The turtles later drive Zach to his home, and Zack shows his bigger brother the turtles sitting in the Turtle Van.
