A bunch of high school chums get themselves deep into the ghost-hunting thing. They met the supernatural, the Ulanaya, a spirit that takes many forms. Malevolent but only after going through years of exposure to the evils perpetrated by humans. This is what the Ulanaya acquires after absorbing all the negative thoughts, acts and deeds of humans it has come across with through the years. In the process, the Ulanaya then musters the ability to take many forms such as the wind, fire, water, earth and others making it the ultimate elemental and its malevolence, most potent. A force to reckon with especially on the gang of amateur ghost hunters, the Spirit Warriors do battle against this behemoth of an elemental, the Ulanaya.
Against the advice of a concerned mythology professor, a group of school friends decide to take an out of town trip during the holy week. When they first leave on their vacation, Shiela, Rina, Christian, Kerwin and their friends believe they have made a good decision. Everyone is happy and excited about their upcoming adventure. But soon, the mood starts to change. Shiela begins having dreams and premonitions about an evil presence somehow related to young children. She sees images of an old woman that terrifies her. Troubling, frightening events seems to multiply around them. The friends soon begin to believe that one of them may be the source of the evil that is plaguing them. Will one of friends have to sacrifice themselves in order to protect the others?
