College girl Pearl (Pauleen Luna) is delving into the horrific history of her school when a female spirit clad in white starts following her. Who is she, and why is she so tormented? Soon, the torturous events surrounding the incessant bullying of a young girl named Christina (Angelica Panganiban) surface, and the details show that Pearl might be implicated in the mystery far more than she wants to be.
