Feeling forced to face her past, Jessica tries desperately to maintain the invisible wall she's hidden behind for years. But when the question about her daughter pops up again, Jessica feels her sanity threaten to unravel as the meager life she's built is put in mortal danger and all fingers point to that fateful day, four years ago, when Jessica discovered what it means to truly suffer."
