He's growing up overnight!

When scientist Dr. Simon invents a genetic transformation machine, evil business men scheme to steal his billion dollar idea. But before they get the chance, Dr. Simon’s two-year-old grandson accidentally turns his body into a thirty-year-old man and runs off. Now his siblings must catch him and figure out how to change him back before their parents get home – and before the bad guys get to him first.
