Ophthalmologist Sun-jae is obsessed with shoes. It is her sole form of solace as she tries to come to terms with her husband’s disaffection and her daughter, Tae-soo’s, indifference. After catching him with another woman, Sun-jae leaves him, taking Tae-soo with her. While waiting for the subway train one day, Sun-jae finds a pair of red shoes. Strangely fascinated by them, she takes them home. But it is not just Sun-jae, but her daughter too, who is mesmerised by the red shoes. Unknown to either of them, the shoes beget its wearers a ghastly end.
