I ask you, grant me this favor... to be the third in your bond! Damon sets out to murder the cruel King Dionys. The attempt fails. Upon his capture, he is sentenced to death by crucifixion. Damon does not plead for his life, but for a grace period of three days to perform one last service for his family and to marry off his sister. As a pledge, Damon's friend remains behind. If the deadline passes by sunset on the third day before the condemned's return, the guarantor must die in Damon's place. Chased by the ticking clock and the fear for his beloved friend, Damon embarks on a journey fraught with unforeseen dangers and obstacles. Will he manage to return in time and save his friend from certain death? Who does not know Friedrich Schiller's famous ballad "The Guarantee.".
