Directed by Larysa Kondracki, making her feature film debut, The Whistleblower has an impressive cast, including Rachel Weisz, Vanessa Redgrave, David Strathairn, Monica Bellucci, Benedict Cumberbatch and Luke Treadaway.

Larysa Kondracki co-wrote the script alongside Eilis Kirwan.

Below, you can read the official synopsis, and then watch the trailer:

Kathryn Bolkovac (Weisz) is a Nebraska cop who is thrust into the gravelly snake pit of UN regulated Bosnia. She works as part of a private corporate army, training Bosnian police to restore order to the war-torn country. As she begins to get the lay of the land in her new environment, she starts to see signs of a terrible underground industry whose patrons are not only from within the corporation but from within the United Nations as well. After finding a woman who has escaped from a human trafficker selling sex slaves to hidden brothels in the area, Kathryn begins to see how expansive an industry it has become in the years following the war. As she gathers more and more evidence to bring to light she discovers the last thing she ever expected, that there is no way for the corporate army and UN officers to be held accountable for their actions. Based on the harrowing true story of a single womans quest for justice in the face of a truth no one wanted to expose and organizations facilitating the very crimes they were created to stop. But is one woman enough to go up against the United Nations and its corporate conspirators.

The Whistleblower does not yet have a distributor, so a release date is currently unknown. However, with a cast list this impressive, expect a studio to snap the film up in the not too distant future.
