His father jumped off a cliff, his mother was depressed, and his sister Liu Xiaoge lost contact on the cruise ship she was on. Liu Dahui resolutely left his job and went south to investigate alone. After arriving in the Cocos Islands, he was in trouble. He met Brianna by chance and learned that his mentor Katerina was also investigating the missing cruise ship, but his mentor refused to meet him.
The old gypsy man saw through his purpose. The female reporter claimed that she had information and wanted to cooperate with him, but she secretly set up a trap and the two of them were drugged and took nude photos. Brianna broke up after seeing this and was kidnapped by terrorists. Liu Dahui tried his best to save her, but was shot and warned by Katerina.
Meng Zheng, a boy from Skull Island, picked up a lever with a battery, and the signal attracted the terrorist organization - they wanted to retrieve the spy's body that contained the space weapon chip.
Pirates and terrorist organizations arrived at the same time. The fishermen discovered Meng Zheng's distress signal and teamed up with Liu Dahui to hunt for treasure. They were chased by the pirates. Liu Dahui found Brianna and learned that Katerina had been kidnapped. The fleet lost its way on the high seas, and the fishermen evacuated one after another. They were left to continue moving forward. They were pursued by a scientific research vessel and the fishing boat lost control and floated.
The fog cleared and they stopped at Skull Island, where gunfire was intensive. After landing, he found Meng Zheng and learned that his sister was still alive and that the savages on the island were the missing tourists. The terrorists failed to find the chip and forced the tourists to hand over the murderer. Liu Dahui sneaked into the scientific research ship and fought fiercely. Qiu Wei flew a helicopter to support. Mohan Moda killed Katerina, stabbed Brianna, and detonated the ship.
Terrorist reinforcements arrived, and while everyone was fighting fiercely, an earthquake and volcano erupted on Skull Island. During the evacuation, they were besieged by more than a dozen pirate ships and State M agents on the high seas. At the critical moment, Chinese warships and helicopters came to the rescue.
