Now they are faced with the choice of what their future, together or alone, will look like. Kreuger is developing a revolutionary future plan for the Netherlands. Although he has many opponents, Kreuger is determined to follow his heart and intuition this time. Samir does not see a single future. It becomes increasingly clear to him: the prime minister is responsible for his loss.
