Wanting out of high-stress detective work, Simon Brenner takes a calming job as a chauffeur, shuttling a two-year-old girl back and forth in a soothing ride along the Autobahn between her father, a construction tycoon in Munich, and her mother, an abortion doctor in Vienna. Except then one day he stops at a gas station to buy the little girl a chocolate bar and comes back to find she's been kidnapped ... and suddenly he's out of a job, thoroughly stressed out, and a detective again.
