Soo-Yeong is a senior student whose ideal life is being an artist, but that goes down the drain when her mother goes to jail for allegedly slaughtering her father. She and her brother now live taking care of each other, studying and trying to facilitate their dreams while also striving to uncover the real killer of their father-if there is one. As they try solving the mystery of their father's crime, the otherly ghosts "living" in the house, caring and telling the story seek answers to understand why they've been silently observing this family's affairs for two whole generations.
