Overview

When the app is launched, a ghost appears. Developed by four young adults, the app becomes the centerpiece of a livestream where they venture into a supposedly haunted mountain to prove its authenticity—only to meet a grim fate. This chilling event kicks off Unlock, a horror anthology composed of seven short episodes. The series begins with App the horror, followed by The Night Bus, which unfolds on a long-distance bus; Ominous House, which features a ghost-conjuring ritual; The Collector, about the brutal fate of a man who watches an illegal video; Snuff Film, revolving around a vengeful director whose footage was censored; Sweat Home, where a woman's return to her family turns into a nightmare; Haunt, featuring a man paralyzed from head to toe who begins to see ghosts; and Dawn Call, about a group tasked with cleaning up a murder scene in the dead of night.
