Carmel Monserrat (Kim Chiu) belongs to an "espirista" group called P.E.K.T.U.S. Her team tries to help clients with problems dealing with the supernatural and other spooky matters. But here's the thing -- it's a fraud -- they only fool people into believing that they actually shoo away the ghosts. Now, a certain Jack Colmenares (Enzo Pineda) hires P.E.K.T.U.S. to exterminate the ghosts in his house, and he will pay them one million pesos if they are successful. While doing their fake job, P.E.K.T.U.S. is faced with real spirits. And so their real horror adventure begins.
