In a post-World War I Germany, a group of political prisoners finds itself confined in a dark military prison. Among them is Emil, a rebellious intellectual who refuses to submit to the regime's oppression. One night, a series of unexpected events force the prisoners to confront their own inner demons as they struggle to survive in a hostile environment.
The plot thickens when a band of insurgent soldiers attempts to free Emil and his comrades. Amidst the confusion, a series of confrontations erupt between the prisoners and the guards, revealing the hidden tensions and loyalties that exist among the characters. Each prisoner has their own story, from the former government official obsessed with redemption to the young idealist who believes in a new revolution.
As the night progresses, the prison walls begin to crumble, both physically and emotionally. Conversations turn into confessions, revealing secrets they have kept for years. Fear and hope intertwine, and in every corner of the cell, questions about loyalty, betrayal, and the fight for freedom arise.
In this dark night, the prisoners are forced to confront not only their oppressors but also themselves, as they struggle to find light in a world that seems doomed to despair.
