Sony Pictures Classics has picked up U.S. rights to “In Darkness,” the latest film from helmer Agnieszka Holland.

Based on Robert Marshall’s nonfiction book “In the Sewers of Lvov,” storyline follows a thief in 1943 Poland who hides a group of Jews from the Nazis in the sewers of the town of Lvov. Although the thief initially helps the refugees for purely mercenary motives, his conscience eventually gets the best of him.

Pic, penned by David F. Shamoon, stars Robert Wieckiewicz, Benno Fuermann, Maria Schrader and Herbert Knaup. The Film Works, Schmidtz Katze Filmkollektiv and Zebra Films produce.

SPC, which also released Holland’s film “Olivier, Olivier,” snagged rights to “In Darkness” from sales agent Beta Films. Company’s slate also includes recent pickups “The Guard,” “Take Shelter” and “The Greatest Movie Ever Sold.”
