In this live-action comedy, Leo inadvertently accesses a high-tech wall panel in the "smart home" he shares with his inventor stepdad, Donald Davenport, and his mom, Tasha, that sends him plummeting into a secret underground lab where he discovers three teen super-humans -- Adam the strong one, Bree the fast one and Chase the smart one. The three, eager to leave their confines, convince Leo to take them along to school, where they try to navigate the world of high school life while managing their bionic strengths. Along the way, they help Leo build confidence in himself, and figure out a way to keep their bionic abilities a secret from the world with a few occasional glitches.
