An ordinary, run-of-the-mill salaryman, Satake Hirofumi, goes on a cruise with his business client, Kito Joji. They spend a fun time out on the sea, but the cruiser gets destroyed when a whale crashes into it. Satake and Kito evacuate on a lifeboat, but they're adrift alone in the Pacific ocean. Provisions and water gone, they're on the verge of death. The only thing left in Satake's hand was a gift from his fiancée, Negishi Chie: A lucky coin pendant.
In the sea, there are fish 
that can harm humans,
،في البحر، هناك سمك يستطيع أذيّة البشر
Das Meer birgt Fische
wie Haie und Schwertfische,
En el mar, algunos peces son peligrosos,
En el mar, algunos peces son peligrosos,
En mer,
les requins et les espadons
Nel mare, ci sono pesci
che possono fare del male agli esseri umani,
No mar, há peixes como
 tubarões e peixes-espada
В морях водятся рыбы,
опасные для человека,
