Nowadays, in the sea south of Japan, a huge fishing vessel intends to defy the bans and make a fortune from whaling. However, just as they were about to make a good take, something else got in the way, something very ancient and very powerful.

Horrified by the pollution of the oceans and the overfishing endangering many animals, Scylla sinks the ships of all those who endanger its environment. Rumors of a sea monster spread and a ship leaves for its supposed territory, a very special hunter with the ambition of neutralizing a mythological beast endangering humanity. But, far from any civilization, it sometimes happens that the worst monster isn't the one we think of at first glance.
