Ask about a European movie. In the classroom experiment, imagine that students were near the center of the nuclear explosion. There was a fallout shelter that could only accommodate 10 people, and only 10 out of 21 people could survive.

I only saw one paragraph, and it was probably about a teacher doing an experiment in class. He asked his students to imagine that they were near the center of a nuclear explosion and were exposed to nuclear radiation. There was a fallout shelter that could provide oxygen and some food for 10 people a year. It could only accommodate 10 people. After entering the fallout shelter, one would not be able to open the door without the escape code. Every student had an identity card. According to their identity, 10 useful people would be voted to survive, and the remaining 11 would die from nuclear radiation. There were teachers among the 10 people. The teacher killed the 11 useless people and was rejected by the remaining 9 students who could live in the fallout shelter. The teacher asked one of the female students outside the door for help and wrote a note: " I'm the only one who knows the escape password." However, in the end, no one agreed to let the teacher in. In the end, the teacher died of nuclear radiation. The nine people living in the fallout shelter tried to open the door of the fallout shelter in various ways, but they could not open it. In the end, the nine people died one by one.
