En 2018 la Radio Televisión Suiza invitó al colectivo Bande à part, que integran los cuatro reputados cineastas Ursula Meier, Lionel Baier, Frédéric Mermoud y Jean-Stéphane Bron, a llevar a la ficción un suceso que les hubiese marcado profundamente. El resultado es esta mini-serie antológica que retrata cuatro crímenes atroces que conmocionaron a la sociedad suiza, sobre todo por la implicación en ellos de niños y adolescentes. 
The simplest method to measure an athlete's vertical jump is to get the athlete to reach up against a flat wall, with a flat surface under his/her feet (such as a gym floor or concrete) and record the highest point he/she can reach flat-footed (the height of this point from the ground is referred to as "standing reach"); fingertips powdered with chalk can facilitate the determination of points touched on the wall. The athlete then makes an effort to jump up with the goal of touching the highest point on the wall that he or she can reach; the athlete can perform these jumps as many times as needed. The height of the highest point the athlete touches is recorded. The difference between this height and the standing reach is the athlete's vertical jump.
