Some patients don't go home. Some patients don't die.

After twenty years, local police captures the murderer of the older brother of a young boy. Now a doctor, he must go back to his old town and face the murderers himself. He then discovers that the murderers are Aswangs (folkloric Filipino vampire-like creatures) and they pose a deadly threat not only to him but also for the entire town.
