Young teenager Leo Dooley's mother, Tasha, gets remarried to billionaire inventor, Donald Davenport, and they move in with him. While trying to find his bedroom, Leo accidentally discovers teenage siblings with bionic powers living in their basement. Leo secretly takes them to school for the first time and the show follows the bionic teens as they unravel in adventurous situations in an attempt to live life like a normal family in the fictional town of Mission Creek, California. As the show progresses in Seasons 2, 3, and 4, it gets darker with the introduction of Davenport's younger brother Douglas (turned good in Season 3), Douglas' android son Marcus, Victor Krane, S-1 (later joins the Davenports in Season 4), Sebastian (formerly known as S-3) and Krane's bionic soldiers, and Giselle.
By Season 4, Davenport opens a bionic academy called the Davenport Bionic Academy on a bionic island to train Victor Krane's bionic soldiers to be the world's newest heroes. The Lab Rats meet their fourth sibling, Daniel, whom Douglas put up for adoption after Donald rescued the kids from him. However, they face off against Giselle Vickers, Douglas's ex-colleague and ex-girlfriend who resurrected Marcus and attempted to eliminate the Lab Rats and bionic soldiers and replace them with androids.
