Ever since Adam (Jim Sturgess) and Eden (Kirsten Dunst) fell in love as teens, their bond has faced astronomical odds. The pair are separated not just by social class and a political system bent on keeping them apart, but also by a freak planetary condition: they live on twinned worlds with gravities that pull in opposite directions�he on the poverty-stricken planet below, she on the wealthy, exploitative world above. Their budding but illicit romance screeches to a tragic halt when interplanetary-border patrol agents catch them and Eden suffers an apparently fatal fall. But when, ten years later, Adam learns she is alive and working at a vast corporation whose towering headquarters connects their planets, he sets out on a dangerous quest to infiltrate the company and the upper world to reconnect with her. "Upside Down" is a visually stunning romantic adventure that poses the question: what if love was stronger than gravity?
