It's about humanity, family, thriller, suspense, ignorance, psychotic, trust.. all in one drama.

This drama will touch your heart,
You'll be sad, angry, and think that everyone got what they deserved.

Ryu Sung Joon, a dedicated detective, longing for his family attention and love, especially from his brother Ryu Song Hoon, which he adores so much.

Ryu Sung Hoon, a dedicated judge, has lots of pain in his heart, always keep distance from everyone, and keep everything inside. Later on found that he's a survivor from Hope Children Center.

A case of murder made the brothers work together coz Jung Soon became a suspect.
However, along the way, lots of secrets revealed, more people being killed, and it is somehow related to their past.
With the help of Eun Ki, a female social worker, they investigate and try to clear Jung Soon's name.

Every episode starts with flashback of the children's camp, which always make me brokenhearted, sad, angry and hurt.
How cruel and sadistic the camp was, and how no one cares.
Finally the camp was shutdown on 2002, and the revenge starts 20 years later.

I won't say much into details, but i'd say : I LOVE IT! A must-watch drama.

PS :
there are actually children/teenage camps which torture the kids, even now.
I remember Paris Hilton shared her story when her parents sent her to a 'disciplinary' camp, where she'd actually been mentally and physically abused. No one even know how bad it was, not even the parents. We should be aware of places like that in real life.
