Following its debut as part of the 2016 Berlin International Film Festival, director Sebastian Hilger's We Are The Tide (Wir Sind Die Flut) will hit German screens next month. And as part of the lead up to public release a full theatrical trailer has just arrived that is absolutely loaded with beautiful and puzzling visuals. Here's how Berlin described the film: Fifteen years ago the sea disappeared from Windholm’s shore. The tide simply retreated and has remained out ever since. There were no recognisable causes, it just happened. From that day this anomaly has lain like a curse on the area, throwing up questions and causing disquiet. Two young physicists, Jana and Micha, set out to get to the bottom of this mysterious phenomenon.
