S-Signal

Star PD Choi Ji-Hoon’s new entertainment program, S-Signal, gathers a diverse group of participants at a love house. Idol actors, sexy BJ streamers, models, yoga instructors, and baeksu all arrive with the goal of joining the show. To them, S-Signal appears to be the opportunity they were promised—a high-profile production bringing together entertainment figures and ordinary hopefuls under one roof. What the participants do not know is that the set has been arranged around a very different reality. Contrary to the official premise, all kinds of conspiracies are being planned behind the scenes. Sex and voyeurism are part of these hidden schemes, transforming the love house from a shared stage for the show into a site of manipulation and secret observation. As the production moves forward, the participants remain unaware of the forces working around them. S-Signal follows their gathering under false expectations and the dark, calculated designs that the set conceals, where the line between entertainment and exploitation is deliberately blurred.
