Tomasz Komenda was 23 years old when his normal life was brutally interrupted. Overnight he was arrested, thrown into prison and charged with murder. Subsequent expert opinions confirmed his participation in the crime, and any evidence was against him. For nearly two decades in prison, he was beaten, intimidated, humiliated and on his own. Finally, after 18 years of imprisonment, prosecutors and a policeman appeared on his way, who decided to discover the truth behind the mysterious case of the detainee.
