Prisoners (2013)

It definitely is not going to be an easy task to watch this film without questioning your values.

When Keller Dover's daughter and her friend go missing, he takes matters into his own hands as the police pursue multiple leads and the pressure mounts. But just how far will this desperate father go to protect his family?

Haunting, suspenseful, and masterfully acted, Prisoners has an emotional complexity and a sense of dread that makes for absorbing (and disturbing) viewing.
