In the 1930s, the German realist painter Koelz, created a massive anti-war painting called 'Thou Shall't Not Kill'. It heavily criticised the foreign policy of the Nazis. Koelz and his family were forced to flee Germany, in order to escape arrest. Koelz' painting was cut up at a local saw-mill and the pieces were scattered throughout Germany, some given trusted friends until the day war was over. Seven decades on, attempts are made to reunite the fragments of the painting and reconstruct this lost work of art.
