Bree is just like any other teenage girl, except that she has super speed and stealth! These don’t always come in handy when all Bree wants is to fit in at school and be popular – but with her Lab Rat brothers and Leo around she’s always got a helping hand to call on.
Adam is the strongest and biggest of the Lab Rats, but he’s also the dumbest! Always speaking and acting before he thinks. One thing’s for sure – when Adam’s around laughs are aplenty.
Chase is the youngest and smallest Lab Rat, but don’t let that fool you as he’s also the smartest! A super big brain doesn’t guarantee him an easy path through high school though and he doesn’t always get humans right, which leads to hilarious situations for all the Lab Rats and especially Leo.
Leo has just moved into a new house with a new family that has come complete with 3 new siblings, but these aren’t normal teenagers – Leo’s new step-dad has invented the world’s first Bionic Superhumans! With this major life upgrade Leo’s world is about to be turned upside down as hilarious adventures abound with his new family. Leo’s determined to help his Lab Rats siblings fit in at high school, but when you mix superhumans with teenage life, fun and adventure come thick and fast.
When 14 year old-Leo moves into his new stepdad’s mansion, he snoops around and discovers his stepdad’s secret project; Adam, Bree, and Chase - three bionic siblings (each equipped with hi-tech apps) living in a lab beneath the house! An unlikely friendship develops as he sneaks them out to school for their first taste of freedom while they help him to become the most popular kid in school. But when their bionic glitches go off, things get chaotic very quickly...
