Marty McFly thought he'd seen everything on his trip into the past - but it was nothing compared to what he was going to find in the future!

He'd only just got back from fixing things in 1955 when Doc Brown reappears in his customized time-travelling DeLorean to whisk him through time again - to 2015, where Marty's son is about to get into deep trouble.

But fooling with time is a risky business. And when Biff, the neighbourhood bully gets his hands on a piece of the future, past and present start changing - into nightmare.

Only Marty can change things back - and it's - literally a race against time!
