Introduction: There is a secret snake breeding base on the outskirts of Haixi. One day, a ferocious group of snakes escaped from the cage and began to frantically attack the humans in the snake breeding base. At the same time, the snake group also crawled towards a flight attendant school not far from the snake breeding base. The school is preparing for the graduation ceremony, and students who do not know that they are about to face danger are still conducting the school's professional skills competition. The group of snakes secretly poured into various places of the school. Several girls were bitten by the group of snakes. The screams alarmed the entire dormitory building, and the girls fled. The security guard Liu Chao rescued Li Mengna, a flight attendant major who was trapped by the snakes. The two wanted to notify the teachers and students of the school to evacuate urgently, but were stopped by the principal. In front of everyone's eyes, the giant black snake devoured the principal in one bite, kicking off the great escape of the human and snake. Seeing that the students of the giant snake were running around in disorder, Liu Chao and Li Mengna decided to come forward and lead the other girls to escape the danger of the snake group.
