The issue begins with a flashback to fourteen months prior to the current events in the ongoing series. At StockGen Specimen 6 (a snapping turtle) is being injected with mutagen derived from the contaminated version present in Old Hob's blood. Chet Allen and Lindsey Baker are conducting the experiment. By one month in to the experiment the turtle had more than doubled in size, and he was primed to begin psychological conditioning. By five months in it is strong enough to take on a whole squadron of men. Its physical development has been progressing much faster than its mental development, making controlling it difficult. Two weeks before current series events, it escaped from StockGen. The previous night, Michelangelo was getting pizza from Woody Dirkins. The two talk for a few minutes before Mikey leaves and they agree to meet at the same time the next night. After Mikey leaves, Woody is attacked by the escaped StockGen specimen, trained to hunt down the Turtles. Currently, the Turtles are investigating the scene of an attack. Witnesses report a "big, green lizard" and "deadly force authorized". Leonardo says they need to hurry up and found another underground hideout before they get blamed for the attacks.
The Turtles make their way to check out a potential hideout found by Donatello and April, and Raphael reminds him they're on a tight schedule because he has to make it to Casey's first ice hockey game on time. On the way the Turtles talk about Splinter's "Destroy Shredder Manifesto", wherein he said while the Shredder lives they will never have peace. Michelangelo says he went by the pizza shop earlier but Woody wasn't there, meaning the Turtles would have to eat Splinter's salty vegetables and rice for dinner.
Back at the Turtle's current hideout (April's parents' old antique shop), Splinter is cooking salty vegetables and rice. He asks Casey to turn the television on so he can watch his stories. But when Casey turns the TV on, the news is reporting the series of attacks going on in the city (including the one on Woody at Rupert's Pizzeria), deemed to be the work of a vandal called "Slash" by the local media. Just then April comes in, telling Casey and Splinter to come look at her van. April's van had been attacked by Slash. April deduces Slash to be the escaped speciment from StockGen.
While the Turtles are on their way to check out the new hideout they stop to interrupt a mugging, and they are twice referred to as "Slash monsters", emphasizing the need for them to find a safer hideout to avoid a case of mistaken identity. As they flee scene after disposing of the thugs, Slash arrives at the scene, hot on their trail. He catches a glimpse of them and tears of part of one of the thugs' shirts, fashioning himself a black bandana like the other Turtles'. The Turtles arrive at the potential hideout, an abandoned church with a nuclear fallout shelter underneath. The Turtles are checking out the dark bunker with flashlights and decide the place is perfect when Slash arrives. Once inside he attacks. He eventually knocks out Donatello and Raphael and is about to take out Leonardo.
