Future Boy Conan

On Remnant Island, a tiny surviving enclave of humanity on the devastated Earth, Conan lives alone with his grandfather until a young girl, Lana, washes up on the shore. Two soldiers of Industria land their hydroplane and kidnap Lana. While threatening the intruders with a missile, Conan's grandfather is mortally injured when one of the soldiers opens fire on him, detonating the launcher.

After Lana is kidnapped by the two soldiers from Industria, Conan fails to rescue her. Conan's grandfather dies from his injuries. After burying his grandfather, Conan builds a boat and sets off to rescue Lana.

Conan arrives at an island where a wild boy, Jimsy, lives. After an initial fight, Conan develops a good friendship with Jimsy. The Baracuda comes to the same island, getting the inhabitants to salvage for plastic. After Conan finds out the Barracuda is from Industria, he and Jimsy plan to stow away aboard the ship.

Jimsy and Conan sneak onto the ship, but Jimsy gets drunk and alerts the captain of their presence. After the boys are caught, Captain Dice lets Conan and Jimsy stay on the ship if they will take punishment. Jimsy passes out and Conan takes both their beatings. They work on the ship doing random jobs. Finally, the ship sets sail for Industria.

After the Barracuda arrives in Industria, Conan is thrown in the brig after he assaults Monsley who was visiting the ship. Lepka, the self-serving chief administrator of Industria's High Committee, tries to threaten Lana into telling him where her grandfather is. Monsley decides to take Conan in for "re-education". When the soldiers come to take him, Conan escapes and, after a rough flight through the bowels of Industria, eventually finds Lana.

While making their escape, Conan and Lana come upon a plane from the last war that Lepka wants to power with Dr. Lao's solar energy process for his plans of world conquest. They are captured, and Lepka threatens to hurt Conan if Lana doesn't tell him where her grandfather is, but she refuses. Upon witnessing Lepka's viciousness, Dyce decides to help Lana. Dyce and his crew kidnap Lana and make their escape on the Barracuda.
