A catastrophic event occurs and all the buildings in the world get sucked up into the sky. A few years later, Patema, a vivacious girl who lives in a base camp, falls into a hole while exploring a dangerous area. Patema "falls" from the underground to above ground and continues to almost fall into the sky. She is saved when she manages to cling onto a boy named Age who is above ground. The two children with opposite gravitational forces, support each other upside-down and learn about each other`s worlds in the post-catastrophe era. In doing so, they learn hidden terrible truths that they begin to confront. As Patema and Age travel to and from each other`s worlds, they must support each other while being upside down or they will fall. A truly unique sci-fi fantasy that almost numbs our own senses of up and down that creatively depicts the beauty of love, friendship and courage.
