Four detectives – with one goal: to find the missing person! Alive and unhurt. Always fighting a ticking clock. The first German fictional TV series to play along with a second screen. In this application for tablet or laptop an image of each character pops up on the screen in the same moment as the person appears on TV. The user can then judge on a digital whiteboard: is this character a criminal or a victim, is he a friend or a foe of the missing person? A heat map gives an immediate feedback how the community judges the character at this very same moment. Judgments for every character can be altered as long as the case is not solved on the TV screen.
