Watch Sadisflix. Filmmaker Emma Boelhouwer has no affinity whatsoever with darts. Until she is zapping on TV one night and ends up in the middle of a nerve-racking darts game. She is seized by the look on the face of the young, still unknown darter Michael van Gerwen and knows right away: this fellow from Noord-Brabant will become a star. She rushes headlong - with her camera - into a world that is completely new to her.
