"The Red Shoes" is based on the classic fairytale of the same name that centres around the theme of vanity. In this adaptation, we follow a divorced mother named Sun-jae, who moves into an apartment with her daughter, Tae-su. While riding the subway one day, Sun-jae finds a pair of bright pink heels and decides to take them home, but she's unaware the shoes are actually cursed and cause those around it to become greedy. Sun-jae's best friend, Kim Mi-hee, becomes affected by the shoes and steals them, but she ends up dying shortly afterward. Sun-jae tries to get rid of the shoes, but she soon discovers that they follow her wherever she goes.
