Mirai Shounen Conan (Movie)

After war submerges most of the continents, Conan grows up with an old man on an isolated island. Finding Lana changes everything: forces from Industria pursue her to control her scientist grandfather and his knowledge of solar energy. When she is taken and Conan loses his guardian, he leaves the island to rescue her.

With his new friend Jimsy, Conan reaches a city dominated by Lepka's ambition to rule the survivors. Escapes and rescue attempts converge around its triangular tower as Lana becomes a bargaining piece in a struggle for power. Conan refuses to let the world's remaining people fall under another destructive regime.
