01PLOT

In Oroku Saki's palace, Hun tells Saki about the "turtle costumed freaks." Saki is angry for the Turtles having foiled his plans too many times. He accuses Hun and Baxter Stockman of screwing up and allowing the mutants to ruin things. The angry Foot leader orders the pair of underlings to cooperate for a change to find the Turtles, uncover their secrets, and if necessary, destroy them.

Meanwhile, Splinter is teaching the TMNT a lesson about the “Way of Invisibility”. The training session is not going too well when Casey Jones arrives at the lair unexpectedly (and uninvited), causing things to go from bad to worse as Jones becomes the annoying guest who would not leave. However, Casey did come for a reason, to show the Turtles pictures of the graffiti going up all over the city that threatens the Turtles. Casey wants Raphael and the others to go topside and teach these disrespectful taggers a lesson, but the ninjas smell a trap and tell Jones the bad graffiti is not worth troubling about. The Turtles return to their training as Casey kicks back, showing no sign that he intends to leave anytime soon. Eventually, Splinter has Raphael bring Casey up to the surface while the others continue their training lesson.

When Casey and Raph get up to the surface, they happen upon several Purple Dragons spray-painting more graffiti. Casey and Raph easily defeat the three Dragons, but suddenly reinforcements arrive - Baxter Stockman's Foot Tech Ninja - and they have the power of invisibility! Raph correctly deduces that these bad guys are wearing cloaking devices that make them invisible to the naked eye. Both Raph and Casey are knocked out. The Foot Tech Ninjas take Raphael, but leave Casey to the Purple Dragons to deal with.

When Raphael comes to, he discovers that he's strapped to an examination table, surrounded by probes and other medical equipment, in some sort of lab. Hun and Stockman are observing him. Seeing Raph gain consciousness, Hun begins to question him, while Stockman stays in the background waiting for his chance to dissect this strange creature.

In the meantime, Casey escapes the Dragons and returns to the lair and explains what happened to Raphael. While the tale of invisible ninjas is a little hard to swallow, there is no denying that Raph has been kidnapped, so the crew heads out to find their missing brother by using the transponder in his Shell Cell to

track him. Donatello hands out his new "Turtle Vision" goggles, which should allow them to at least see thermal images of the invisible ninjas.

As the guys are heading out in search of Raph, he quite unexpectedly and easily manages to escape. When the fugitive Turtle climbs the stairs from the lab, he discovers that he's on a yacht in the middle of the Hudson River. No problem, since Turtles are amphibious! Raph jumps off the ship and swims to shore. Watching his escape are Hun and Stockman. It turns out that the escape has all been prearranged by Hun in the hopes that Raphael will lead the Foot Tech Ninjas to the rest of the mutants. Hun explains to Stockman that his invisible soldiers will follow Raph without him even knowing he is being trailed, reminding him that he better hope the Foot Tech Ninjas don't fail their mission.

Raphael and the others meet up in the sewer tunnels far from the lair, and assume all is well until suddenly they are under attack from invisible forces. Don instructs everyone to put on their Turtle Vision goggles and they are able to see thermal images of the Foot Tech Ninjas. With the odds now evened, the Turtles and Casey are able to defeat the Foot and return home to the security of their lair.

Hun and Stockman are now left to deal with Saki’s wrath once again due to another botched mission. However, based on his brief interrogation of Raphael, Hun tells Saki that the turtles don't know anything about Saki’s enemies, the Guardians, let alone work for them. Saki decides that the Turtles could potentially be of use to him when the time comes for him to confront his enemies.

A Guardian spy reports to a trio of odd individuals that the strange Turtle creatures are apparently not aligned with Saki, at least not yet. The trio tells the spy to learn all he can about these creatures, and they will wait for more information before taking any action against them.
