Rachel Weisz is set to star in the indie political drama The Whistleblower, in which Larysa Kondracki is making her feature directorial debut.

According to Variety, the film is based on a true story which chronicles the trials of a female cop from Nebraska who serves as a peacekeeper in post-war Bosnia and exposes a United Nations cover-up of a sex trafficking scandal. Kondracki and Ellis Kirwin wrote the film, which will shoot in Budapest. The pair based the screenplay on the story of Kathryn Bolkovac, who traveled to Bosnia in 1999 as a U.N. peacekeeper.

The project had originally been set up at Focus Features, where Kaufman had been an exec on the project. Then HBO Films scooped up the real-life tale in turnaround.

No production date has been set.
