Seon Jin finds no place of solace. At school, he is mercilessly bullied because of his unnervingly quiet demeanor and frail appearance. Yet, this is not the root of Jin's overwhelming dread: what he fears above all else is his own father. To most people, Jin's father appears to be a successful businessman, a good samaritan, and a devoted parent. But that is just a facade; in reality, he is a deranged serial killer—and Jin is his unwilling accomplice. For years, they have maintained this deception while the police remain unaware. When his father becomes interested in the attractive transfer student Yoon Kyun, Jin faces a choice: be the coward who sends her to the gallows like all the others, or be the bastard son who defies his wicked parent.
