When Theodore Pine Four suddenly appears in the bedroom of Genevieve Corrigan just as her friend Jules Santorini is about to ask her out on a date, the only thing they can all agree on is that it is highly unordinary. Things get even more complicated when we find out that Theo is a teenager from the year Fourteen Billion and Seventy-Three with multicolored hair, a talking coat, and the hottest new time machine on the market: the TimeMaster JumpMan Pro. And little do they know that this chance encounter is going to kick-start an epic adventure -- one that will take Jules, Gen, and Theo through history, from the Big Bang all the way up to 14,000,000,073 and everywhere in between. Along the way, our heroes are going to have to figure out how to get Theo and his malfunctioning time machine back home without undoing the fabric of time itself. And, if he's lucky, Jules might just manage to ask Gen on that date.
