Watch on 123Movies. Students attending the Science and Technology University, located far from the city, conduct experiments in the campus laboratory during summer school. However, during the experiment, things happen that the students did not plan for. As a result of mistakes made, an explosion occurs, exposing the young people to gas and causing them to undergo a kind of mutation. Students who were not in the laboratory and were not exposed to the gas see their friends and think they have turned into creatures.
