Leo's lifetime gets less ordinary when, one day, he discovers a secret underground laboratory that houses three experiments: super-human teenagers. The trio -- Adam, the strong one, Bree, the fast one and Chase, the smart person -- convinces Leo along with his parents to let them leave their laboratory and join Leo at school, where they decide to make an effort to match while being forced to manage their unpredictable bionic strengths.
