Trumpet player Géza Elekes does not play very well in his private life, and his fourth marriage has failed. One day he gets a call from his father, whom he hasn't spoken to in decades. This prompts her and her son, András, who is in the thick of things, to visit her parents, who live across the border. When he arrives in Transylvania, his father says he is fed up with her jealousy and moves in with him. Géza reluctantly accepts the idea, but eventually the three men set off for Budapest. Along the way, they face many trials and tribulations: hit-and-runs, chases, women, corpses and the green border.
