A colleague goes mentally ill when he goes undercover to investigate a prison where a mastermind is in order to uncover a conspiracy of an organization. In order to save his comrades and uncover the darkness, Sho disguises himself as a male prison officer and infiltrates a women-only prison. I should have been able to hide the fact that I was a woman in a situation where I didn't know who the prisoner, prison officer, colleague was, and who was the insider... A fierce battle begins in a cage where no one comes to help. *Bonus footage will be recorded after the main story ends.
