"It is, in a way, a classic ticking clock kind of suspense thriller," says Jackman. "It will absolutely, 100-percent keep you on the edge of your seat."

Set in New England at Thanksgiving, Prisoners follows small-town couple Keller and Grace Dover (Jackman and Maria Bello), whose jovial get-together with good friends (played by Terrence Howard and Viola Davis) is ripped apart when their daughters suddenly disappear. Despite help from police and a detective named Loki (played by Jake Gyllenhaal), there is insufficient evidence to detain the prime suspect, Alex Jones (Paul Dano), the driver of a dilapidated RV seen at the time of the two young girls' disappearance.

With time running out and few other options, Keller takes matters into his own hands to try to save the children. But is it justice, or has he just become a vigilante?
