A ship is running in the South China Sea in extreme cold. The task of Captain Benica's trip is to help people transport a batch of goods, and all the expenses of the voyage are paid by a behind-the-scenes person. There are also a group of mercenaries guarding the cargo under the cabin. The captain's assistant Cantoson accidentally discovered that they were transporting torpedoes, but they found out that they were beating them up and were finally saved by Benica. Unexpectedly, their ship broke down and a cruise ship was found not far from the radar, so they had to go there for help. At the same time, not far from them, the luxury cruise ship "Agonotika" is making its first voyage. Simon Ryder is the owner of this ship, and it cost $480 million, making it the most luxurious cruise ship in the world today. Luxury cruise ships are full of wealthy and jewelled ladies and rich men. Trillian, a beautiful female jewel thief, was mixed into the ship. She was arrested while stealing expensive necklaces and put in a closed luggage compartment. On the way, Simon secretly stopped the running program, all the operating systems were paralyzed, and the ship came to a complete stop, because Simon didn't want to hand over the ship he had worked hard to build to the banker. Unexpectedly, a group of unidentified objects emerged from the depths of the ocean at a very high speed, destroying everything on board. The group of mercenaries arrived by speedboat and planned to rob the cruise ship. They didn't trust Benica and Cantoson, so they took them with them. After the mercenary boarded the ship, he found that all the passengers had disappeared, only blood was everywhere on the ship. When they searched the ship, they found Trillian, the female burglar, and Simon, the owner. At this time, everyone decided to escape from the cruise ship together and return to Benica's speedboat. And the huge monster suddenly appeared. This group of monsters is a mutated underwater creature. Every tentacle of the monster has become a scarlet mouth full of fangs, which looks very frightening. They only suck liquid things, so everyone on board is drained of blood and bone marrow. Mercenaries are used to risking their lives, but they are all shocked by such a horrible phenomenon. Everyone worked together to escape, but everyone was playing their own small abacus and guarding against others. On the way to escape, Simon deliberately pointed out the wrong way for everyone, and on the way, mercenaries were swallowed up by monsters one by one. Bennika and Terry found a perfect motorboat under the cabin, and used it as a tool to escape from the luxury cruise ship "Agonotica". Simon and the giant monster died in the fire together.
