Dianne works as a part-time tutor for the Gonzales family, the owners of a funeral parlor said to be the lair of rumored aswangs.

On her first day, she meets the patriarch Carlo, the children - Ryan and Sarah, butlers Aludia and Simeon, and the secretary Anna. After a series of successful tutorial sessions, it gradually became clear to Dianne the nature of the family: being photophobic, having a desire for entrails and other unusual activity in and out of the parlor.
