BY A SHARP KNIFE is inspired by the still-unsolved murder of young student Daniel Tupý by neo-Nazis in Slovakia in 2005. In this compelling film, a father, Ľudovít, loses his son to a ruthless neo-Nazi attack. The perpetrators are arrested, but because of a legal loophole, they are released. Ľudovít then struggles with an apathetic police force, an opportunistic judge, and his guilt over his relationship with his son in a devastating fight for justice.
