There's a peeping Tom prowling the neighborhood. Eyewitness reports vary, but one thing is agreed upon: he wears a Devil mask.
This is the story of Val Castillo, a promising gymnast with a strange hobby. She is secretly the neighborhood peeping Tom. At first she is alone in this, but when a male friend discovers her doings, he joins her into a dark journey of spying and making discoveries about their neighbors that may have been better left alone.
