A Friend of Mine

Karl (Daniel Brühl), a quiet insurance man, is sent to a car rental service his boss thinks is crooked, with orders to watch it from the inside. What he finds there is Hans (Jürgen Vogel), a coworker who talks nonstop and never seems to notice that Karl would rather he didn't. Sebastian Schipper follows the two from Berlin to Barcelona, and Karl slowly stops minding the noise.
