Former undertaker and ex-police officer Luc Conrad comes back to Switzerland to attend a birthday party in a hotel. When the hotel manager dies under mysterious circumstances, he secretly begins to investigate whether it was a murder.

His last big journey took him from Stein am Rhein to faraway Japan. Theo Plakoudakis and Marco Salituro had developed the script especially for Mathias Gnädinger. And so the popular actor filled the role of "Big Summer" with a lot of heart: The former wrestling king Anton Sommer is forced by the ten-year-old boy Hiro to accompany him to Japan. Hiro wants to become a sumo wrestler like his father. Zurich-based Stefan Jäger has staged a modern fairy tale that becomes an endearing homage to Mathias Gnädinger. He died on Good Friday 2015.
