Detective Woo Ji-Man becomes deeply embroiled in the case involving Lee Na Mi and Oh Jun Yeong because all murder cases point to his son as the perpetrator. We are also confronted with a scene where the mother and son are in contact. However, delving deeper, we discover that Oh Jun Yeong is pretending to be the son, as the real son was Oh Jun Yeong’s first victim. Due to the strained relationship between father and son, the father remained unaware of his son’s whereabouts. Ultimately, the truth is unveiled: the son is deceased, and the mother, who believed she was in contact with him, was actually communicating with Oh Jun Yeong. This revelation occurs when the father discovers his son’s phone and finds a wallpaper depicting the son on water, evoking deep emotions of sorrow and lamentation.

How does the story conclude, and what role does Lee Na Mi play in ending the ordeal with Oh Jun Yeong?

Lee Na-Mi, along with her father, is captured by Oh Jun-Yeong and confined inside the bathroom, both bound and submerged. The detective arrives at the right moment and rescues them both. Lee Na-Mi regains consciousness quickly, but her father, remaining submerged for a longer period, struggles to regain consciousness. With the detective urging him to breathe, it seems unlikely he will survive. As the bathroom door opens, Lee Na-Mi, lying on the floor, overhears Oh Jun-Yeong attempting to negotiate with Detective Woo Ji-Man while the latter angrily holds him at gunpoint. This fills Lee Na-Mi with fury. She strides over to them, wrests the gun from Detective Woo Ji-Man’s hand, and shoots Oh Jun-Yeong. Subsequently, she hears her father’s voice calling out to her. In shock, she turns around, rushes towards him, and embraces him, shedding tears as she cries aloud.

Does Unlocked conclude with a happy ending?

The Korean movie indeed concludes on a happy note, intertwined with an open-book conclusion regarding the perpetrator. Lee Na Mi and her father are rescued from drowning by Lee Na Mi herself, who then shoots the perpetrator, Oh Jun Yeong. Detective Woo Ji-Man uncovers the truth about his son. However, there remains uncertainty about the fate of the perpetrator, as he has yet to awaken. A cautionary lesson about the dangers of such circumstances is imparted. The movie ends with a text message being sent to another person regarding finding Kirke’s coffee shop, where Lee Na Mi works, prompting a response requesting a picture, leaving viewers in suspense once again and indicating a probable Unlocked part 2.
