Sae Fujiki is a married woman who runs a bar in Tokyo, having inherited it from her mother. Her husband, a regular customer who owns a construction company, won her over partly through his income, but she keeps running the bar because she loves talking with people. One day a customer in the porn industry shares behind-the-scenes stories and sparks her curiosity about performing. Her husband's poor bedroom skills and her ongoing dissatisfaction make the opportunity even more tempting.
