Joo Eun-ho was only 17 years old when he was sentenced to life in prison for brutally murdering his two adoptive parents. He was tried as an adult. The court refused to consider his confession that his adoptive father had sold him into prostitution when he was 14.

Over the years in prison, Eun-ho endured a harsh life and grew accustomed to same-sex relationships. Thanks to his good looks, he became the favorite of the prison gang leader, Kim Seung-jae, who offered him protection.

On his 27th birthday, Eun-ho suddenly learned that someone had moved heaven and earth to reopen his case, hired top-tier lawyers to defend him… and finally got him out.

Eun-ho never imagined that on the first snowfall in December, he would step out of prison. He had no purpose, no money, and no idea where to go. The only life he knew was inside the prison walls.

What must he do with his life now? And who was so adamant on getting him out of prison? What did they want from him?
