“RXN” – in chemistry it is an abbreviation for “reaction;” which is the essence of this drama that turns into a pulse pounding thriller. A serial killer is loose. But he lingers not in the shadows of the night. Rather, he walks the streets in broad daylight, a free man, amidst people who know nothing. But Rita knows. Her sister was one of his victims. Try as she might to put the past behind her she can’t. And after the killer returns to terrorize her niece and nephew, she decides to take matters into her own hands. She baits him to follow her at night to a hiking trail where she intends to turn the tables on her aggressor and the hunter becomes the hunted. A story of payback and revenge, “Natural Reaction” will have the audience reacting in shock when the “killer ending” is revealed. Writer: Eric Nemoto. Pages: 90.
