Shinkai No Survival 2021

Geo, Phoebe, and Dr. Gong board the Ammonite Submarine for a deep-sea survey. On their way down to several thousand meters of depth, they get caught in some methane gas bubbles, and the Ammonite Submarine breaks down. Now, they can no longer contact Kay, who's up on the surface. Then, a huge sperm whale and giant squid attack, and Geo ends up getting separated from the group! Phoebe and Dr. Gong go to rescue Geo, but the Ammonite only has a little bit of energy left…

Meanwhile, Geo is surrounded by deep-sea creatures on the pitch-black ocean floor! Will they manage to make it back safely from their extreme deep-sea situation!?

"I'll be sure to survive, just wait and see!!"
