Trở Thành Kẻ Giết Người - To Be The Killer (2018)

Lee Si-myung's 'To Be The Killer' transcends the conventional crime thriller, offering a profound psychological examination of criminal intent and moral ambiguities.

It's a potent work that provokes significant contemplation on societal prejudices and the devastating repercussions of desperation.
