Das Geheimnis von Murk(2008)

Murk, a village in the middle of nowhere. There live the Gerbers, a couple who have dropped out of society, scraping by and definitely more left-wing than right-wing. Felix still loves Sarah as much as he did on the first day they met, but what began with a spontaneous trip to India together has now become a psychological and existential test of endurance for both of them.
