999-9999

Sun is a student who doesn't believe in love and leads a tight-knit, mischievous clique at a Phuket international school. The group exudes easy confidence and a shared hunger for thrill, sometimes flirting with danger. This dynamic sets the stage for the dark curiosities that follow when Rainbow arrives.

Rainbow transfers from Chiang Mai and instantly shifts the group's dynamic with her enigmatic presence. She radiates a chilling allure that unsettles the clique even as she draws their curiosity. Her arrival introduces a new spark that will drive the later tragedies.

Rainbow shares a chilling tale about a demon summoned through the number 999-9999. She warns that speaking it after midnight grants a wish but exacts a deadly price on the caller. The others dismiss it as superstition, yet the legend plants a dangerous seed.

Chi challenges the legend after midnight and wakes to a Ferrari waiting for him, a stroke of luck that feels almost magical. The sudden fortune hints that the number's influence is real, not just a story. The ominous turn foreshadows more dangerous consequences to come.

Meena wishes to become Channel V Thailand VJ, hoping to rise above the rest. Soon after, she is found dead by hanging at a party, the tragedy chilling the group. Her death marks the first clear pattern of the number's deadly toll.

Sun begins investigating the deadly calls and spends more time with Rainbow, drawn by both fear and curiosity. He senses a dark truth behind the legend, even as he tries to deny his own lingering desire for love. The investigation tightens the tension around Rainbow and the group.

Rajit aggressively seeks to shed his geeky image and chase danger, stepping further into the deadly game. A sudden fire burns him, turning ambition into tragedy. The fire confirms that testing the number has a mortal cost for everyone involved.

Moo Priew, hoping to justify his place in the clique, tries to lose weight but ends up falling from a window. His body is found thinner, his organs pulled out in a grotesque display of the number's toll. The gruesome event compounds the sense that no one is safe.

Wawa dreams of becoming an astronaut-in-training but is crushed by a brutal accident where sharp gears rip through her head. The accident shatters the group's fantasized future and intensifies fear within the circle. It becomes another brutal reminder of the price of chasing wishes.

Driven by an unacknowledged longing, Sun dares to call the number and wishes for love. Rainbow appears, kisses him, and for a moment it seems his wish has come true. But this awakening carries a chilling implication that love will be bought at a terrible cost.

Sun locks Rainbow away in the familiar tower where the group congregates, hoping to contain the danger. From his surveillance setup, he uncovers a cruel truth: Rainbow is the architect behind the deaths, using the number to lure and eliminate others as a devil's apprentice. The discovery shifts Sun from longing to dread.

Rainbow vanishes, and the phone line promises Sun his own doom. A heavy box drops from the tower toward Sun; he narrowly dodges it, then a pipe pierces his chest, ending the fight and his life. The climactic moment seals the brutal culmination of Rainbow's deadly influence.

A flashback reveals Rainbow's past at another school, where she first told the girls about the number. The chain of deaths begins there, including a girl impaled on a flagpole, linking the tragedies across schools. The revelation shows the pattern of fear stretched by Rainbow.

The film closes with the haunting realization that Rainbow's whispered power has followed her across communities, leaving fear and unanswered questions in her wake. Viewers are left with a sense of an enduring, elusive threat that extends beyond any single school or time. The ending lingers, suggesting the danger can recur to new victims in unseen places.
