The Constant Gardener actress Rachel Weisz is set to star in an independently produced political drama based on true story. Whistleblower, based on the story of Kathryn Bolkovac who traveled to Bosnia in 1999 as a U.N. peacekeeper, will follow the trial 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, according to Variety. Larysa Kondracki, who will make her directorial debut in the film, co-wrote the script with Ellis Kirwin. Filming will be held in Budapest.
