Leo tells Adam that if he could be in two places at once, then his duplicate can do his training for him. Adam then wishes he could duplicate himself so Eddy shows Adam and Leo the cellular duplicator. Adam makes a duplicate of himself and makes his duplicate go to school for him. But when Adam's duplicate finds out that Adam doesn't have to go to school, the duplicate duplicates himself, and so on. Then there are many duplicates of Adam roaming around the house. Meanwhile, Bree and Chase are told by Principal Perry to show her niece, Carrie around the school. Carrie behaves like an angel around Principal Perry but around Bree and Chase she is rude, and tells Bree and Chase to do her homework for her and pretend like they were watching over her while she ditched the classes. Then Principal Perry tells Bree and Chase to watch Carrie again, this time at their house. Carrie leaves and tells Bree and Chase to pretend like she was there the whole time. Meanwhile Adam and Leo are having a hard time getting rid of Adam's duplicates, so they turn to Chase for advice and he uses a zapper to zap the duplicates in order for them to leave. Principal Perry comes back to their house to pick up Carrie when there are many duplicates of Adam, and Chase zappes them all away, but there is one more duplicate left, and they try to make sure that Principal Perry doesn't see him, then they zap him. In the end they find out that one of Adam's duplicates got away and is working at a pizza delivery place.

RAT 215 PERRY20 EPISODE 73d94d2f-e17b-429b-b1c9-6be6e1271234 10003436 220x124
Mission Creek High is too old of a school, since the equipment is too old, and the textbooks seem to date back to the 1700s-1800s. Leo and Chase decide to do something to update the schools system, which leads to Mr. Davenport to want to help. They first say no, that his ego would get in the way. They eventually gave in. The school is updated with everything being electronic, and it's great for everyone, until Mr. Davenport made a robotic version of Principal Perry, because he wanted a wing with his name on it in the school. Everyone begins to hate Leo and Chase, which leads to them reprogramming Robo Perry before the school board sees it. Meanwhile, Adam and Bree try to prove that the new foreign exchange student, Allister, is a bionic spy, because Marcus was the new kid, and he turned out to be a bionic spy. They end up freaking him out and accidentally hurting him. The final straw comes when Adam accidentally picks up a whole shelf of weights. Since Chase and Leo tampered with Robo Perry, she reset to the original military use: search and destroy. She is attacking everyone on the school board and Principal Perry, which almost leads to Adam, Bree, and Chase revealing their bionics due to Davenport's orders, but before they can, Perry tackles Robo Perry, and rips her head off, so their secret is safe. In the end, it turns out Allister is not a bionic spy (due to evidence that made Adam and Bree think so, such as him being able to do different accents perfectly like Bree's vocal manipulation, and catches things with perfect reflexes, and uses terms that sound like he's an android), and all of the dodge balls Adam threw at him made him lose his memory of anything after dodge ball. Allister then shows Adam and Bree his dodge ball team made of exchange students. They throw balls at Adam and Bree and walk off.

Adam and Chase are always pulling pranks on each other, to which Bree keeps getting caught in the cross fire. The final straw comes when Adam meant to dump 50 gallons of expired milk in Chase's capsule, and accidentally calibrates it for Bree's. Davenport tells her to prank them back. She tries, but ends up getting caught in her own prank by Chase tricking her. Davenport tries to help her, only for Leo's Grandma to be caught in the crossfire. Donald then becomes her assistant. To get out of it, he makes her a scooter to ride around in. When the boys try to prank Bree, Tasha becomes the victim of the boy's prank. Tasha and Bree prank them the next day, to which it works. They offer them cookies, which has different things in it, not made with real cookie ingredients. They pick up their controllers which have glue on them. The controllers and the boys fly up when the giant magnet was activated. They demand Tasha and Bree let them down, to which Bree agrees, only to find that she let's them down into Adam's chunky milk and Expired meat. Meanwhile, Leo and Janelle keep trying to spend time together, only for Leo's grandma, Rose, to keep coming to keep Leo away from Janelle, most likely do to jealousy. Rose doesn't like Janelle, and does things like insult her, and go through her phone. When Rose gets hurt, Leo takes this as a great sign for him and Janelle to spend time together. Things quickly go back to bad when Rose gets the scooter. While Janelle distracts Rose, Leo programs the scooter's GPS for "home", allowing him and Janelle to spend time together. When Leo gets home, Donald asks where Rose is, and Leo says she should be home. They find out it was accidentally calibrated for Mission Creek, Illinois instead of California. Rose is shown on the highway in front of a truck. In the end, Leo and Donald wheel Rose in with a wheelchair, only for her to get caught in the giant magnet that Adam was playing with, and what Bree and Tasha pranked Chase and Adam with.
