The plot of a play

In order to do hormone research, the school professor experimented with a large number of animals, which caused some students' considerable dissatisfaction. Animal-loving students, while holding slogans to protest against invalidation, broke into the professor's laboratory with the intention of destroying experimental equipment, only to be attacked by a group of rats who ate experimental hormones by mistake. Since then, the whole city has been shrouded in an atmosphere of panic. Until the reason is found out and the rats are completely eliminated, the war between people and rats will end.

The plot took place on a university campus. A professor did an experiment to increase auxin in tomato, and the result was eaten by a mouse that was shut aside, so the mouse began to become huge. It happened that several college students who came to the laboratory at night accidentally opened the cage. Deaths began to occur on campus. Finally, the protagonist used his own mouse to attract all the mice together, and then the police drove all the mice away.
