In Seoul, three women in their thirties meet while working mundane office jobs at a snack manufacturer. Eun-sang, the eldest of the group, is always looking for ways to earn extra money, but faces trouble at work after she opens a mini mart at her desk. Jisong dreams of a perfect romance with her Taiwanese boyfriend and spends her low salary on trips to Taipei. Meanwhile, Dahae is struggling to support her injured mother, and searches endlessly for a better apartment she can actually afford.

One day over lunch, Eun-sang announces a plan to make enough money to quit her job, by investing her life's savings in cryptocurrency. What's more, she thinks the others should join her. All they need to do, she says, is hold on tight and wait for the price to skyrocket - to the moon. But as the market begins to fluctuate and spiral out of their control, the fate of their friendships - and their futures - soon hangs in the balance.
