Petr studies law in Prague, Jakub studies philosophy there. They are the best of friends until their holiday trip to Slovakia is crossed by a Romani young man named Imro. Imro is in love with Eržika, who is guilty of breaking an ancient tradition by breaking her vow of loyalty. The vow is the law. In a fit of jealousy, Imro kills his beloved. Two punishments await him. One from the majority "white" society, the other from his own Roma community. Petr and Jakub watch Imro's tragic fate from close proximity and their views on the matter of justice and punishment begin to diverge diametrically. The academic controversy eventually escalates into a fundamental conflict of life attitudes that almost destroys their friendship. Whose side is the truth on?
