When his mom marries a geeky billionaire inventor, Leo discovers that he has three bionically enhanced teenagers living in the basement of his new home.
When Donald arranges to send his three bionically enhanced teenagers to a remote facility, they take measures to remain and keep their new best friend Leo company.
Donald permits his bionic teens to attend high school, but getting on the bad side of school football bullies triggers Chase's macho alter-ego to emerge and put them in their place.
When Donald and Tasha leave for a trip to Australia they leave Leo & the bionic kids home alone. Leo accidentally activates one of Mr. Davenport's devices which causes the bionic kids to glitch.
When Tasha complains about Donald's addiction to technology, Donald proposes a tech-free beach day. Unfortunately, an incoming solar flare requires the bionic trio to remain in the RV/mobile lab instead of enjoying the beach.
While Leo aims to take on the 5-time school one-on-one basketball champ with some technological help, Adam auditions for an open spot on the cheerleading team against Bree.
Jealousy arises when new student Marcus bonds quickly with Adam and Chase and the three form a band together, but Leo's antipathy turns out to be more justifiable than first thought.
Marcus wheedles himself into staying with the Davenports over the same weekend that an emergency necessitates Donald sending the superteens into space.
