Harry Pattler is a law student who works as a late-night taxi driver in order to pay for his studies. He argues with Professor Olten over how reliable circumstantial evidence can be in court. To prove his point he begins to investigate the background of an ongoing case against a man who faces conviction for murder on purely circumstantial evidence. Harry is able to prove that not only is the man not a murderer, his supposed victim is still alive.
