Every afternoon at exactly 3:13 PM, the school bell at Brunswick School rings three times instead of once. Most students ignore it. Teachers call it a glitch. But Ivy, Lukas, Liam, and Neta know there's something more to it. When they decide to stay after school to investigate, the mystery deepens. Strange whispers, eerie footsteps, and a long-abandoned swimming pool with a dark past pull them into a chilling adventure. Is it a malfunction, a prank, or something far more sinister? To uncover the truth, they must face their fears, follow the clues, and step into the unknown… before the bell tolls again.
