Twenty-seven-year-old Lin Mo was lovelorn and unemployed, and fell into a low point in his life in Wancheng, Nanyang. After being introduced by his fellow villager Zhao Lei, he joined a community supermarket called "Mart-Mart" to work. This small shop with an inconspicuous appearance is not just a daily necessities retail store. The store manager Zhou Qiang has a complete profit-making routine to harvest middle-aged and elderly customers.
On the one hand, there is easy money and attractive commissions that far exceed ordinary part-time wages. On the other hand, there is a gray business model that deliberately deceives the elderly. Under the pressure of livelihood and inner entanglement, Lin Mo, a young man at the bottom, is deeply involved in this sales scam targeting middle-aged and elderly people. In the trivial daily life and the game of interests in a small town, he faces the dilemma of survival and conscience.
