Cell 211 is a Spanish movie. The film tells the tragic story that happened between prison guards and prisoners in the prison. Juan is a newly recruited prison guard. He excitedly reported to the prison in advance and was allowed to visit the prison in plain clothes. Unexpectedly, he encountered a prisoner riot. The evil mother in Cell 211 is the leader who instigates the prisoners to riot. They rioted in order to improve the life of the prisoners in the prison, and even kidnapped the prison guards to force the government to agree to their request. Juan was involved. In order to learn more about the prison and the prisoners, he did not reveal his identity, but continued to mediate between the police and the prisoners. In the gradual contact, Juan discovered that the leader of the prisoner was actually not bad at heart, and his demands were not too much. Juan's conscience began to tilt towards the prisoner. But this was inconsistent with his identity as a prison guard, so Juan fell into hesitation. At this time, his wife came to visit after hearing the news, but the prison guard beat his wife indiscriminately, causing the pregnant Liujia to die. His wife was killed instantly, which made Juan even more disappointed with the government and prison authorities. The prison is also preparing for a conspiracy. They pretended to agree to the prisoner's request, but secretly prepared a bloody suppression. In the end, Juan also died in this chaos
