Joy is a forensic science major and when she thought that it would be easy when she graduates, she was wrong. It's been 6 months and she's still unemployed. Living in a rundown apartment with her dog, Haetnim, with 4 different part-time jobs isn't easy especially when your landlord is planning to kick you out for no apparent reason. Desperate for money, when she finds herself waking up next to Wendy, a wealthy woman, she accepts the offer to "help" the woman in exchange for money. But there's one problem: Wendy is missing with the price of a quarter of a million dollars and it seems like the cops are after them.
