Synopsis
One night, a blackout occurred when May and Jublek are at their tutoring school in Siam Square. Later, they realized that it is not just the building but a blackout in the entire Siam Square. When the lights came back on, they're reminded of the tale of a girl that mysteriously disappeared in Siam Square many years ago. It is rumoured that her spirit has haunted the place, and every time there's a blackout, she will appear to take someone with her. May, Jublek and their group of friends begin to experience unusual incidents, and the myth of the Siam Square spirit becomes more powerful in their minds. Above that, they have to worry about their entrance exam and romantic conflicts that come between them. Siam Square is no longer a fun place. With every strange happening, they come closer to the dark truth. Now they have to face the reality and try to correct the situation before it is too late.
