High school teacher Adam has a secret affair with the dean Catherine, and their intimate video is captured by rebellious student Emily as blackmail, forcing him to become a private tutor in a wealthy family. He navigates between the love-starved girl Emily and the lonely, seductive stepmother Sarah, while being dragged into the money extortion and power-sex entanglements of the rich stepfather Richard and ex-husband David. Layers of secrets interweave, and Adam sinks into a quagmire of desire and conspiracy, holding the evidence of the rich man's money laundering while being restrained and hunted by many sides. After confrontations, prison ordeal, and life-and-death crises, Richard gets what he deserves, and everyone settles; yet a sealed video reveals a hidden truth buried for many years.
