The sins of a father are visited upon the son who has discovered his secrets in this political thriller from director Soren Kragh-Jacobsen. Thomas Deleuran (Anders W. Berthelsen) is a puppeteer who makes his living performing for children. Ironically, Thomas had an unhappy childhood and isn't faring much better either a father or a husband; his marriage is falling apart, and his relationship with his daughter is distant at best. One evening, Thomas gets a call from his sister Charlotte (Sonja Richter), who wants to meet with him, saying she's uncovered some interesting information about their father, who worked in Swedish intelligence. Thomas and Charlotte make plans to meet the following night, but when he arrives at her place, he's informed that his sister died in a drowning incident. Thomas later meets with Ursula (Maria Bonnevie), who was romantically involved with Charlotte and a party to her secrets; between talking to her and reading the notes his sister left behind, he discovers his father was part of a classified biological warfare program in the Eighties, and the knowledge makes him a target of agents who don't want these secrets brought to light. Det Som Ingen Ved (aka What No One Knows) was an official entry at the 2008 Berlin Film Festival.
