Hush (2008)

Ana and Samuel McCloud are a young married couple living in a dystopian town where secrets have become a valuable means of currency. While her husband is idealistic and fiercely opposed to selling out his neighbors for money, Ana occasionally compromises her belief system to ensure the ultimate survival of her family. Driven by a sense of maternal protection, Ana comes to realize that by supporting a corrupt system, she is placing her family in a dangerous situation that far outweighs the uncertainty of being an outcast.
