GKids unveiled the English dub trailer of the anime film Patema Inverted by Yasuhiro Yoshiura (Time of Eve, Pale Cocoon) exclusively on Anime News Network on Monday. The film will open in North American theaters on August 29.

GKids describes the story:

Patema Inverted, from Time of Eve director Yasuhiro Yoshiura, is a perspective-twisting sci-fi adventure about two kids separated by opposite gravities. Patema lives in an underground world of tunnels, the long-abandoned ruins of a giant industrial complex. Though she is a princess, she is held back by the rules imposed by the elders of her clan. One day when she is exploring in a forbidden zone, she is startled by a strange bat-like creature and tumbles headlong into a void and out into the wide-open world above the surface – a place in which Patema risks “falling up” into the sky and being lost forever. Student Age lives on this surface world, a totalitarian society whose compliant population has been brainwashed against the “sinners who fell into the sky.” When Age spies Patema hanging upside-down from a tree, he pulls her down to safety. Once they master the art of navigating competing gravitational forces – their weights cancel each other out – the pair sets out to evade the leaders of Age's world and discover the secret that keeps their worlds apart.

Michael Sinterniklaas as Age

Cassandra Lee Morris as Patema
