International Film Festival Rotterdam (IFFR) 2021 will open with the international premiere of absurdist tragicomedy Riders of Justice by Danish filmmaker Anders Thomas Jensen, starring Mads Mikkelsen. Riders of Justice with Mads Mikkelsen and Nikolaj Lie Kaas centers on the deployed military man Markus who has to go home to his teenage daughter, Mathilde, when his wife dies in a tragic train accident. It seems to be plain bad luck – until the mathematics geek Otto shows up with his two eccentric colleagues, Lennart and Emmenthaler. Otto was also a passenger on the wrecked train. He is convinced someone must have been behind it. As the clues pile up, it becomes clear to Markus that his wife became a random casualty of what looks like a carefully orchestrated assassination.
