30 students Grade 12 class of Crane University has the same students like any other class could have. Brats, populars, heartthrob, bullies, bitches, nerds, goody two-shoes and quiet ones. It was all normal. Until that incident happened... One of their classmates died. Hindi nila alam kung bakit at paano. Nakita na lang nila itong walang malay at naliligo sa sariling dugo, at may kasama itong sulat. "You killed me. Wait for me, I will hunt all of you." 30 students became 29. After years of trying to forget that incident, the soul of their beloved classmate started to hunt each one of them. And the question is... Will they survive?
