Based on the award-winning play, DOUBT stars Meryl Streep as Sister Aloysius, the rigid and fear-inspiring principal of the Saint Nicholas Church School, who harbors an extreme dislike for the progressive and popular parish priest Father Flynn (Philip Seymour Hoffman). Looking for wrongdoing in every corner, Sister Aloysius believes she's uncovered the ultimate sin when she hears Father Flynn has taken a special interest in a troubled boy. But without proof, the only thing certain is doubt.
