Jung-hee, a married woman of eight years, lives in a middle-class new city while raising her two sons (ages 6 and 1). For her eldest son's early education, she enrolls him in a nearby academy run by a native English speaker. James, the academy director from the UK, is well-known in the local 'mom cafes' for his excellent manners and sterling reputation. However, as soon as Jung-hee drops her child off, James approaches her and lures her into a 'special service' area. While the children are occupied with their lessons, a wild orgy takes place in another part of the academy.
