'Peter Bergmann' was a German man who checked into a hotel in Sligo town on a Friday in June, 2009. Nothing too unusual with that you might think. Over the following few days however, he was seen wandering around the town with a purple bag which he would always return to the hotel with empty. On June 15, he checked out and took a bus to Rosses Point, a few days later, his body washed up there. Turns out that in the days leading up to his death he was destroying all traces of his origin and identity and despite a five-month Europe wide probe, nobody knew who this 'Peter Bergmann' was. This award winning documentary, directed by Ciaran Cassidy, tells this unusual yet chilling tale.
