"Dimension Twist" is the fifty-seventh episode of Kim Possible.
Kim becomes concerned when Ron doesn't turn up for Naco Night at Bueno Nacho. She infiltrates his house to find him and Rufus binge watching TV. To her surprise, Ron's father finally got cable TV. She then gets a call from Wade, predicting the call was about a break-in at a top secret lab. Upon meeting two scientists )with Ron reading a TV guide), she asks what was stolen but they insist they can't, claiming that in the wrong hands the stolen device could create a black hole the size of Nevada. Kim and Ron correctly guess that they're referring to the Pan-Dimensional Vortex Inducer, as they explain in sequence how they recovered it from Professor Dementor last year in Las Vegas; Ron complains how he hates a re-run, to Kim's annoyance. Rufus examines a scratch mark on the vault and determines that Shego had stolen the device. Ron figures that it's a trap, but figures that it could be a "trap-trap", in which they fall into the trap and set it against Drakken, to which Kim finds makes sense.
At Drakken’s lair, the villain is inconveniently getting cable TV installed as he inserts the Pan-Dimensional Vortex Inducer into his particle cannon for his "trap-trap" for Kim Possible. However, he get impatient with the cable man for the slow install, forcing him to threaten him with his laser to make the cable man go faster, unknowingly plugging in the cable to the laser cannon. When Team Possible arrive and fall right into the "trap-trap", Wade calls in the warning to late. Shego then tries firing the cannon, only for a vortex to emerge from the TV, causing everyone to be sucked into the world of cable TV.
Luckily, Wade manages to communicate with Kim from within the TV dimension and eventually reunites everyone in what appears to be Drakken's lair, only to learn that they're on another show call Evil Eye for the Bad Guy. The show's star trio give Drakken a total makeover of both himself and his lair. When Shego reminds him of his priority, he brings out a quantum compiler, intending for himself and Shego to return to the real world while Team Possible is left trapped forever. Unfortunately, Wade calls in that Drakken's using the wrong protocol, which results in a vortex that threatens to unravel the very fabric of reality. Kim tries to grab the compiler to stop it but the device gets pulled into the vortex. What's more, all the TV dimensions start appearing before them. Ron and Rufus become delighted to walk into a Bueno Nacho commercial, where they get the perfect naco, the same time, Drakken gets a quantum reverser to put a stop the vortex. Unfortunately, the vortex appears in the commercial and consumes both the nacos and the quantum reverser.
They then get moved to another dimension, called That 1670's Show, where one of the characters was hoping to find a woman to court. Another character then tries to court Shego, at which she demonstrates her powers to intimidate him, only for the characters to bring out their pitchforks, believing her to be a witch.
Kim then gets dumped into an action-drama dimension, where she is attacked by a woman wearing a pink wig, demanding to know where the "device" is. Kim points out that the muscular guard behind her may know. Drakken then walks up the guard, asking if the device is for traveling through dimensions, at which he is grabbed by the throat.
Ron arrives on Emergency Pet Groomer, where the star of the show mistakes Rufus for getting shaved naked and accuses Ron of doing it. Ron tries to tell the guy that Rufus is a naked mole rat, but the star gives Rufus a long cut of hair.
Kim and Shego get thrown on pro-wrestling, where they face Pain King and Steel Toe.
Ron and Drakken arrive on a cooking show, where Rufus is to be cooked as the meal.
Kim and Shego come onto a reality show where they have to bungee jump off a high building. Shego grabs the host and jumps off, followed by Kim.
Ron finds himself interviewing Drakken, who is presenting his new book.
Finally, everyone ends up on a game show, where characters from other dimension have been mashed up. Wade tells Kim that with each passing dimension, reality gets weaker and with a few more channel changes will end everything. He has a way to get Team Possible out, but there's too much interference from the vortex. Ron then realizes that the dimensions are going by the TV schedule and has Wade change it to Ape Island, where he gets a stampede of monkeys to plug up the vortex.
With reality stable, Drakken brings out a repaired compiler, which opens a portal he forces a reluctant Shego through. Meanwhile, Wade manages to zap Team Possible back to the real world. Ron turns to Drakken's cable TV but a glare from Kim convinces him to get addicted to video games for the next little while. Kim then reclaims the Pan-Dimensional Vortex Inducer and remarks that it should be locked up better next time before thanking Wade for his help. Wade then reveals that Drakken and Shego have ended up on a kids' show, where both of them are sat on by a giant puppet after Shego makes a threat.
