Merlin works as an editor and is busy editing a film project when he realizes that he is in a time loop. Every few minutes, time stops, runs backwards, and then starts all over again. Within this time loop, Merlin repeatedly receives the same package, with no sender.

With the help of the package's contents and the message of time traveler Thadeus Moff (Götz Otto), Merlin manages to change the time loop and meets a mute swordswoman named Ava (Jasmin Wagner). Together, the two embark on their journey to complete an initially puzzling task.

Filming took place in the original settings from the film "Das Boot" and a volcanic landscape on Lanzarote, among other places.
