Do-Hoon was sent to his relative's house by his grandmother when he was young and grew up alone. One day, he hears news of his grandmother suffering from dementia and goes to his grandmother's house in the countryside. Do-Hoon, who was defrauded by a friend and was in poor financial condition, becomes greedy when he hears that his grandmother's house is a development zone, but it is in vain when he discovers his father had been locked up in the basement for 30 years. Do-Hoon wants to look good to his father and inherit his grandmother's house. However, his father, Yeong-Chun, starts to harm Do-Hoon's family instead.

Why was his father locked up by his grandmother for 30 years? What happened in this village 30 years ago? The terrible incidents shrouded in mystery, the truth of the tragedy that is gradually being revealed, and the resentment and revenge of the people involved in those events. Will his father, Yeong-Chun, be able to let go of his grudge? Will Do-Hoon's family be able to escape the crisis they accidentally got caught up in?
