Korean Movie Streaming Plot Summary

The story introduces WAG, a fictional streaming platform where creators become the observed and viewers can “approve” or give “stickers,” a virtual currency worth 1 won each. WAG and the creators split revenue 50:50, but if a streamer becomes the weekly top-ranked channel, they take all the revenue, with daily earnings reportedly reaching up to 1 billion won. As a result, so-called “WAGgers” will do anything to claim the top spot.

The current number one is Woo Sang’s crime-hunting channel. Woo Sang (Kang Ha-neul) is a star streamer who investigates cold cases in real time and has built a huge subscriber base. He covers the “Hemline Serial Killer,” who is known for cutting pieces from victims’ clothing, earning the nickname “Hemline Killer.” The murderer targets women in red, strangles them, displays the bodies, and leaves a signature knot and cut clothing at the scene.

Woo Sang and his partner Matilda (Ha Seo-yoon) reconstruct the case of the fifth victim, Han Ji-woo, in a joint broadcast. However, Matilda’s assertiveness and her channel “Matilda’s Vanished Night” quickly rise in popularity, causing Woo Sang’s channel to fall behind.

One day, Matilda disappears. With the help of Matilda’s friend Dasol, Woo Sang suspects Lee Jin-seong (Kang Ha-kyung), an artist who had been obsessed with Matilda, as the culprit. Lee Jin-seong, in turn, suspects KJ5385 (Ha Hyun-soo), a member of Woo Sang’s channel.

In reality, KJ5385 has kidnapped Matilda and taunts Woo Sang, threatening to kill her if she’s not found within an hour. Using his deductive skills and help from others, Woo Sang tracks down KJ5385 and Matilda. But it is revealed that the kidnapping was a staged event orchestrated by Matilda to gain more “stickers.” They earn a staggering 1.5 billion won in just one hour.

Unexpectedly, the true identity of the “Hemline Killer” is revealed to be Lee Jin-seong. Obsessed with Woo Sang’s profiling, Lee Jin-seong commits murders with meticulous attention to detail, seeking Woo Sang’s approval. Woo Sang, in turn, gives meaning and symbolism to the murders on his broadcast, making Lee Jin-seong feel as if they are partners in crime.

However, when Woo Sang’s collaboration with Matilda turns the investigation into a cheap performance, Lee Jin-seong feels insulted and can no longer tolerate it. He helps Woo Sang expose Matilda’s staged kidnapping and find KJ5385.

A confrontation ensues between Lee Jin-seong and Woo Sang, with Woo Sang ultimately prevailing. The film suggests that both Lee Jin-seong and Woo Sang are monsters in their own way. Woo Sang claims he alone can look into the abyss of a monster’s mind, but viewers coldly respond, “You created the Hemline Killer.” The film ends on this note.

Korean Movie Streaming Ending (Spoiler)

During the broadcast, Woo Sang gradually uncovers clues and realizes that the killer is watching his stream live, putting him in unexpected danger. As live streaming and reality intersect, tension and suspense reach their peak, culminating in a direct confrontation with the killer.

At the moment when the line between broadcast and reality collapses, Woo Sang comes face-to-face with his own madness and the reality of his streaming addiction. In a desperate situation, he continues to communicate with viewers in real time, questioning his own life, honor, and the very nature of broadcasting.

Woo Sang fiercely battles to reveal the killer’s identity and expose the truth to the world through his broadcast. However, the killer ultimately escapes, and the film ends with Woo Sang closing his stream. The climax—Woo Sang catching the killer—is the film’s highlight, ending with the memorable line, “Now, it’s really over.”

The film leaves viewers with room for various interpretations, raising questions about modern media, streaming addiction, and the blurred boundaries between reality and virtuality. Is Woo Sang a crusader for justice or an instigator of crime?

Streaming Ending Explained

The film’s twist is that it does not follow the typical pattern of good triumphing over evil but instead ends openly. Woo Sang, who started streaming for money, gradually becomes obsessed with justice and succeeds in finding the real killer, but realizes his broadcast has also fueled further crime.

Though he pursues the truth with his viewers, when he finally confronts the killer, he hesitates, exposing the ugly side of media and himself. The film ends by sharply dissecting “popular content” and “digital madness” in modern society, showing the anxiety and tension of the moment when the boundaries between reality and virtuality collapse. It asks pointed questions about digital trauma and madness in contemporary life.

Based on a True Story?

Streaming is not based on a true story. It is a fictional narrative inspired by digital trends and crime streaming phenomena in modern society.

“Streaming” also explores the darker side of internet culture, particularly the hyper-competitive world of one-person media and content creators. The fictional streaming platform depicted in the film mirrors real-world services, emphasizing the obsession with views, donations, and shock value. The narrative delves into themes of manipulation, fame, and online voyeurism, offering a raw look at how far individuals will go for attention and success in the digital age .

While the film’s originality has been debated—some critics feel it relies heavily on the screenlife format and long takes—its execution and Kang Ha-neul’s performance have been widely recognized as its greatest strengths. The psychological tension is further heightened by supporting characters, including the mysterious Matilda and the shadowy Lee Jin-sung, who add to the film’s suspenseful atmosphere .
