Adam, Bree and Chase defy warnings from Davenport and swap bionic chips. Chase, with Adam's abilities, attempts to use heat vision for the first time and accidentally fries the elevator's circuitry, leaving Leo trapped inside with Principal Perry. After an unsuccessful attempt to return the chips to their rightful owners, the Lab Rats realize they must work together to stop the elevator from plunging to the basement.

Adam, Bree and Chase learn about chores and earn allowance for the first time. In hopes of raising more money, the Lab Rats decide to host a yard sale but they accidently sell an antique jewelry box that Davenport was restoring for Tasha. Meanwhile, Leo and Davenport bond over the latest 'Pig Zombie' movies.
