One early September, a young man known only as F. arrives by train in Hamburg, Germany. Impeccable in manners and appearance, F. soon secures a job, an apartment, a girlfriend, and an environment in which his soul feels at peace. At night, however, he is plagued by visions of violence and cruelty. In time it becomes clear that F. has a past he would gladly leave behind. A cast of characters - most of them women - cannot help but wonder about this handsome foreigner, whose charisma and fluent German are more than a little suspicious.
