Barber Ahn Chang-jin (played by Sung Ji-woo) spends his days running a barbershop that has been in his family for three generations, while his wife, who sells insurance (played by Sung Hyun-a), often dresses extravagantly to meet clients, secretly complaining about her husband’s dullness. One day, the talkative Ahn Chang-jin receives a call from someone claiming to be "Kim Yang-ji," who claims to know his unspeakable secret, raising Ahn Chang-jin's alarm. It turns out that not long ago, Ahn Chang-jin was deceived by a prostitute, and while chasing the scammer, he had an unfortunate car accident... Kim Yang-ji soon confronts him, blackmailing Ahn Chang-jin with the fact that someone died in the accident. Under Kim Yang-ji's constant extortion, the barber quickly falls into debt due to high-interest loans and discovers that his wife has been closely involved with Kim Yang-ji, suggesting there may be another hidden agenda. Ahn Chang-jin hires a private detective, hoping to resolve the situation through violent means, but the situation deteriorates further...
