Veronica (Isabelle Daza), Valerie (Beauty Gonzales) and Venus (Elisse Joson) are three adventurous and sometimes mischievous sisters with their own Vlog channel. Together with their friends: Abi (Aiko Climaco), Gina (Sunshine Garcia) and Lani (Analyn Barro), they decide to go on vacation in the town of "Kalimliman". Incidentally, their uncle, Anding (Niño Mulach) is the town Mayor. Mayor Anding has tour guides assigned to promote tourism in his town. He selects Badong (Paolo Contis) and Entoy (Archie Alemania); his top tour guides; as the official guardians for the visiting girls. Badong and Entoy are getting increasingly frustrated with the meager amount of money that they are getting from their tour guide work. They are constantly coming up with plans to earn more cash. During their stay, the five girls hear about the infamous "Forbidden Island", located somewhere near the town. This island so remote that Mayor Anding has banned all travel to it. The girls ask Badong and Entoy to bring them there so that they can produce a prank video to trick their Vlog's viewers into thinking that they got lost while on vacation. Badong and Entoy agree to the girls' request, provided that they get ample payment for their services. Upon reaching the island, the group discover that weird and horrific experiments were done to the island's former residents; turning them into bloodthirsty zombies. The supposedly prank video project has now become a real-life race to escape the island with their lives. Will they be able to outwit, outlast and escape the zombies or will they become new members of the living dead?
