The ad opens with a yellow background and the NS logo. A white card appears with 'NS Flex' and 'Abonnement' on it. Text appears on the left side of the screen, changing from 'Reis met 40% korting of meer.' to 'Eenvoudig wijzigen of opzeggen.' Different discount cards are shown fanning out behind the 'NS Flex' card. A red circle with 'Maandelijks opzegbaar' appears. The scene transitions to a smartphone displaying the NS Flex app, with options like 'Dal Voordeel', 'Weekend Vrij', and 'Dal Vrij'. A wavy white line animates across the screen.
