Rose Flower, Red Lotus) is a 2003 South Korean psychological horror film written and directed by Kim Jee-woon.

The plot focuses on a recently released patient from a mental institution who returns home with her sister, only to face disturbing events while living with their new unhinged stepmother.

Soon after, she is released and returns home to her family's secluded country estate with her father, Moo-hyeon, and younger sister, Su-yeon, the latter of whom she is protective of.

The next day, Su-mi finds family photos which reveal that Eun-joo was formerly an in-home nurse for her then-terminally ill mother.

She discovers bruises on her sister's arms and suspects Eun-joo to be responsible, which Su-yeon neither confirms nor denies.

Eun-joo's relationship with her stepdaughters further deteriorates after she finds her pet birds killed and her personal photos defaced.

Su-mi is suffering from dissociative identity disorder and is a system with two alters: herself and a ruder, more distant variation of her stepmother Eun-joo.

Meanwhile, Su-mi lies back in her bed and smiles with a rolling tear, finally finding some kind of peace, knowing her sister is still with her in some form.

While her terminally ill mother is still alive, Moo-hyeon engages in an adulterous affair with Eun-joo, when she was still their in-home nurse.

Finding her mother dead, Su-yeon grabs her corpse in shock and begins to shake the wardrobe in a panic, trying to free her.

Su-mi storms out of the house, leaving Eun-joo visibly shaking in the hallway, while Su-yeon cries and struggles under the wardrobe.

In the original Korean folktale, the sisters' names are Janghwa and Hongryeon (Rose Flower and Red Lotus).

Kim Jee-woon originally wanted Jun Ji-hyun to play Su-mi, but she refused the role because she thought the script was too scary.

The site's critics' consensus reads: "Restrained but disturbing, A Tale of Two Sisters is a creepily effective, if at times confusing, horror movie.

[11] Kevin Thomas of Los Angeles Times described A Tale of Two Sisters as "a triumph of stylish, darkly absurdist horror that even manages to strike a chord of Shakespearean tragedy – and evokes a sense of wonder anew at all the terrible things people do to themselves and each other.
