The crew of the Red Ocean, shipwrecked off Taiwan, was mostly rescued, but only the radio operator Toyono was missing. Toyono, drifting at sea, was rescued by a smuggling ship. However, fearing the secret would leak, the leader Inomoto ordered the captain to kill him. But the captain left him a mysterious message to wait at the Ibo Jewellery Store on Okinawa Island before escaping him. Upon arriving in Okinawa, Toyono went to the jewellery store and heard from the owner that the captain said he would wait for a while so that he could definitely return to the mainland.
