Jenny Schultz wakes trapped in a pitch-black basement with no recollection of how she got there. With no outside stimuli, Jenny naturally turns inward and revisits her guilt-ridden past, desperate to figure out which wronged person would be angry enough, evil enough, to do this to her. She must survive her own demons, and then time itself when she finds remnants of previous captives-a plate, a tooth, a bone. Scratched hashmarks in the stone walls around her, leave her to wonder what happens next. What happens after six days?
