From the prosperous fishing port in Cadiz, on the island of Panay, the Philippines, fisherman Joaquin Ramos comes home to discover his pregnant wife, a victim of the evil aswang. Without a thought, grief-stricken, he kills the creature crouched over his dead wife. Legend has it, when one kills an aswang, descendants of theirs will become one, so the curse lives on. The story moves on to a more recent setting in Central Indiana, quaint community of Henderson, and the large metropolitan area of Indianapolis. Two detectives from The Henderson Police Department, Glenda McMahan and Luther Charles embark on an investigation that leads them to a mysterious suspect, Amado Rathbone. Amado, a beautiful, wealthy, and successful chemist working for the billion-dollar pharmaceutical company, Hale Broderick, leads a double life. From the powerful influence of his father's wealth and his recent development of a miracle drug, Divina, Amado will never see the inside of a jail cell. Taking matters into their own hands, McMahan and Charles face Rathbone in full horrific transformation. After Rathbone's demise, another aswang is discovered, this one almost takes the life of Detective Glenda McMahan.
