The Lab Rats plan to gain good publicity by having cameramen film them during a mission, but it turns into a disaster when they fight for screen time. After the mission, the president orders the team to stay away from the public in order to let him settle things down. However, it goes wrong when Leo and Principal Perry are holding back angry protesters who want the Lab Rats gone, and Leo accidentally uses his bionic arm. As the protesters become even more enraged, they try to storm the house; Adam panics and uses his bionic super breath to blow everyone off the premises. However, Chase criticizes Adam's actions and the Lab Rats start fighting. They eventually decide to break the team. Three weeks later, the Lab Rats refuse to talk to each other, but they are forced into action when Krane plans to use his Triton App on everyone in the world. A large battle ensues, pitting Leo, Donald, Douglas, and the Lab Rats against Krane and his bionic army. Most of the soldiers attack Adam and Bree, who manage to take them out. Chase has a one-on-one battle with S-3 and Leo has one-on-one battle against S-1. Donald and Douglas attack the soldiers surrounding the satellite, but Krane keeps them from getting too close. Eventually, the Lab Rats and the rest of the team manage to hold back many of the soldiers, but they are running out of time to stop Krane. Douglas then reveals that the Lab Rats can fuse their abilities to stop Krane. They succeed, blasting Krane into the sky and breaking his control over the soldiers. However, their victory is cut short when they find out that Donald is in serious condition after the battle. Later they find out that after the surgery, Donald is still in a very delicate condition. Leo is made an official member of the Lab Rats and gets an upgrade to his bionic arm.
