Synopsis
Queen Mantis (2025) is a South Korean crime thriller you can watch online on iFILM, built around the worst possible family reunion. Two decades ago, Jeong Yi-shin earned the nickname "Mantis" by killing five men, and she has been behind bars ever since.
Her son, Cha Su-yeol, grew up hating her — enough to put on a police uniform himself. Then a fresh murder copies the Mantis method down to the smallest detail, and a copycat is plainly on the loose. The only mind that reads these crimes from the inside belongs to the woman who committed the originals. So Su-yeol has to sit across from his own mother and ask her for help.
Go Hyun-jung plays the imprisoned killer opposite Jang Dong-yoon as her son, directed by Byun Young-joo. The dread comes from conversation, not chase scenes — interrogations that double as a family quietly coming apart. For fans of bleak Korean thrillers where the monster is a relative.
