The Ox (movie, 1991)

In desperation brought on by near-starvation, Helge Roos kills his master's ox and feeds it to his wife and baby daughter. No-one suspects anything until the meat is finished and Helge tries to sell the hide at a local market. He is spotted by the local vicar and, wracked with guilt, confesses. The vicar assures him that if he gives himself up, he'll be treated leniently, but Helge's sentence is far harsher than anyone predicted...
