Ratas (2012)

Nico and Nani hate each other at first sight. The guilty one has a name, Paul. There are many things that separate Nani and Nico but a giant kitchen knife will make them realize that they have a strong bond in common: neither of them will stop at nothing to get Paul. Because love and sex are red... so is blood. And in this Slasher virgins don't need to survive.
