Queen Mantis

What terrifies Detective Cha Su Yeol more than the criminal he must catch is the mother he must join forces with. Twenty years after the arrest of ''The Mantis,'' a ruthless serial killer, a copycat crime emerges, mimicking her methods. To track down the culprit who seems to dig into his own past, Su Yeol reluctantly partners with his mother Jung I Sin, who he has despised all his life. She is a paradox of cruelty and twisted love who slaughtered five victims without a shred of remorse. Yet Su Yeol comes to realize that she holds the key to the case. As the pursuit unfolds, another side of Jung I Sin is revealed, forcing him to confront a terrifying question, ''Am I just another monster that is no different from my mother?''
