Gerhard Wismuth is said to have killed his two children. The press takes up the case and does good business with the grieving mother Brigitte. Then the trial takes a surprising turn: The accused incriminates his wife, who allegedly has a lover and murdered the children for his sake. The TV movie is reminiscent of the "Weimar case".

At the beginning of the 16th century, the Christian Martin Luther followed his calling and became an Augustinian monk in Erfurt. However, his life in the monastery confronted him with his fears of a judging God. These were finally taken away from him through the study of his religion, which emphasized a merciful Creator. As a theologian in Wittenberg, he then went public with his 95 theses, which criticized the church's practice of forgiving sins in exchange for money. A momentous dispute began.
