Magazine editor Pang Shijia and his colleagues went deep into the mysterious uninhabited jungle to shoot materials. They were chased by poisonous snakes and accidentally entered the underground snake palace. The three people who escaped by chance met an injured old man and heard the legend that the bloodthirsty snake king and humans agreed to protect the land and water. When the group decided to leave the jungle, they were hijacked by snake catchers, so they had to show them the way to the snake palace. The snake catcher set a trap to kill the snake king. The snake king was furious and started a killing spree. Pang Shijia and his team repaid the evil with kindness and saved the only surviving snake catcher. The snake catcher who witnessed his brother being swallowed by a giant snake regretted it and decided to leave the mountain with Pang Shijia and his team as soon as possible. However, they were seen by poachers wandering in the forest with the expensive snake skin shed by the snake king. The poachers waited for an opportunity and prepared to force Pang Shijia and his team to take them to find the snake king with a gun. The life-and-death crisis was imminent. On the other hand, the snake king led hundreds of snakes to attack people. How many people can escape successfully from the snake's mouth?
