Mary O'Brian is a nursing student. She's struggling to make ends meet but it's proving difficult to pay her rent and tuition. She's never had any real luck and has no family to fall back on. She's tempted by the lure of being a cam girl, a girl who videos herself for Johns that pay good money for this strange type of entertainment to fulfill their fantasies. Should she, or shouldn't she? It's tempting, it's free and it pays well. But at what cost? Mary's world is about to get very complicated as a dark and sinister force becomes obsessed with her, watching her, waiting for the right moment and for Mary to go too far.
