Someone brutally murders Young-hoon’s wife. A hair sample was found on his wife’s body and the detectives use it to trace it back to his friend Joon-sung and locks him up. Seemingly becoming a murder’s wife overnight, Da-yeon asks Young-hoon to testify on his behalf but when he doesn’t show up for the trial, she goes to visit him at his house.

The Culprit follows the desperate struggle of a man looking for his wife’s real murderer and a woman trying to prove her husband’s innocence. How risky is the co-operation of strangers who conceal their real agenda and the whole truth? Through a repeatedly twisted storyline, this film explores the weak and selsh nature of those who are swayed on the border between good and evil. (MO Eun-young)
