Deep DownSeason 1

In the first episode of "Deep Down", six participants, including Knossi, descend into their own "grave": narrow, dark boxes where they are meant to spend 100 hours. Somewhere between nerves and excitement the doors close – how will they react to their new home?

Knossi, Ronny and the other participants are confronted with the possible consequences of their time in the box, and the first traces begin to show. Ronny turns amateur psychologist while Knossi struggles with fatigue, and then a test awaits them all: who will see the light?

In episode 5 of "Deep Down", rest finally seems within reach, but Sascha's body starts to protest. As Knossi and the other creators try to cope with the void without any routines, an unexpected object shows up – what is it all about?

In episode 7 of "Deep Down", the participants wait anxiously in their boxes underground for the consequences of a decision they made earlier. The cramped space, the emptiness and the endless hours wear on everyone, and a new challenge demanding focus and logic is on the way. What will it all do to their bodies and minds?

With the first participant already recovered, five creators, including Knossi and Lewin, remain in their boxes in episode 9. Hunger and boredom shape their days while a threatening force of nature stirs up fear and uncertainty – how will they cope?

In episodes 11+12, Knossi, Lewin, Ronny, Sascha, Willy and Fibii face a deeply personal challenge that pushes some of them to their emotional limits. Sascha opens up and shows his vulnerable side while painful memories surface for Willy – but what happens down there when Sascha's health starts to take a worrying turn?

Knossi, Lewin, Ronny, Sascha and Willi are in the final hours of their experiment, locked in their tight, dark boxes underground while the mental strain keeps building. How much strength do they have left after so many hours of isolation?
