The people of Aiga are taught to believe that "Inverts," like Patema, are sinners that will be "swallowed by the sky," but Age has resisted this propaganda and decides to protect his new friend. A chance meeting between two curious teenagers leads to an exploration of two unique worlds as they begin working together to unveil the secrets of their origins in Sakasama no Patema, a heart-warming film about overcoming differences in order to coexist.
