Cell 211
Juan Oliver is about to become a prison guard. Trying to make a good impression, he reports for work one day early.
Two colleagues show him around the old prison. All of a sudden, some plaster falls from the ceiling and hits Juan, who passes out.
The guards take him into cell 211, which is empty, to try and revive him.
But a riot breaks out at the high security area, the one that houses the most dangerous inmates. Juan's colleagues run away, leaving him stranded.
When he wakes up in the cell he takes stock of the situation: if he wants to save his life, he must pretend to be a prisoner.
