The internet legend of Smiley—the killer with eyes stitched shut and a mouth carved into a perpetual grin—drives the chilling events of the story.
College students Ashley and Proxy are roommates. At a party, Ashley meets Zane, Mark, and Binder. One night, the two friends test the Smiley myth with a random person. After they type “I did it for the lulz” three times, they witness the stranger being murdered on screen. Proxy convinces Ashley to stay silent, believing they’ve escaped detection, but the fear festers.
Guilt gnaws at Ashley as she becomes convinced that Smiley is stalking her and intends to kill her, a fear dismissed by friends and a psychiatrist as anxious nightmares. She keeps pushing, trying to persuade the police to investigate the murders tied to Smiley, yet authorities dismiss her claims and treat it as paranoia rather than evidence. The strain of the mystery strains friendships and tests the boundary between online myths and real danger.
The danger escalates when Proxy loses contact with Zane, and she calls Ashley in a state of hysteria. Ashley heads to Zane’s house and discovers him shot dead, holding his own handgun. In a desperate, reckless attempt to confront the threat, Ashley takes the gun and orders Proxy to type “I did it for the lulz” three times, hoping to summon Smiley for a confrontation. The plan spirals out of control when Binder arrives to check on Ashley, and she ends up accidentally shooting him. Moments later, Smiley appears and slits Binder’s throat, and Ashley is overwhelmed as multiple Smileys close in, forcing her to throw herself off in a bid for survival. The sequence underscores the dangerous line between internet folklore and fatal real consequences.
A shocking reveal reshapes everything: Ashley’s classmates, including Proxy, Binder, and the babysitter murdered in the opening, are part of a fringe Anonymous group that created the Smiley myth as a large-scale prank. They’re not merely seekers of thrill but perpetrators of a deadly hoax, and they’re satisfied with Ashley’s death as the final product of their game. Binder even predicts that Smiley will endure far beyond their group, inspiring copycat killings and continuing to shape fear.
The moral fallout continues as Proxy and Zane confront the consequences of their actions. In a later video chat, Proxy questions their shared morality, while Zane dismisses her concerns and types the phrase “I did it for the lulz” three times as a cruel joke. The horror intensifies when a Smiley materializes behind Proxy, kills her, and then waves at Zane through the webcam, leaving him to witness the horror in real time.
A post-credits moment offers a chilling reconsideration of the crash of innocence and consequence. Ashley wakes up with a gasp, revealing she survived her fall, leaving the audience to wonder about the true reach of the Smiley myth and who might still be out there, watching.
