The longest night

Psychiatric Prison Monte Baruca. It’s December 24th and it’s starting to get dark. A group of armed men surround the complex and cut off communication with the outside world. Their objective: to take Simón Lago (Luis Callejo), a dangerous serial killer. If the guards hand him over, the assault will be over in a matter of minutes. But Hugo (Alberto Ammann), the prison director, refuses to comply and prepares to resist the attack. His only help will be a few officials under his command and… the psychiatric inmates themselves. A long night of siege and violence begins for Hugo and his people.
