What Happened to Monday

A quiet campsite. Some of the campers here disappear. One day, two sisters Eugene and Yeong-ok come to the campsite to camp. The owner, who cuts and eats raw, dripping meat, takes an interest in the sisters who are camping. The owner, Mansu, kindly takes care of the food separately and tells her to come home and use it comfortably instead of the messy public toilet. The older sister who drank and fell asleep with the purpose of having fun, but when morning came, only her younger sister Eugene remained in the tent, and her older sister Yeong-ok disappeared. Yeong-ok, who is captured and imprisoned by the owner, eats only raw meat without missing a single meal, and her sister Eugene, who is left alone, begins to tremble in fear.
