Now she is alone and scared, stranded on the outskirts of Widowfield, a sleepy little town in eastern Pennsylvania. With Monica's cell phone about to die, Jennifer agrees to rush to her aid. Not wanting to go it alone, Jennifer recruits the help of the only person she can trust: her ex-boyfriend, Chris.
