The Brothers Noltenius.

Wolf Noltenius is a real globetrotter. Early on, this talented young man travelled far and wide, where he earned fame as a construction planner. He moved to Brazil; but one day, homesickness got the best of him. He spontaneously travelled back to his hometown to visit his brother Werner and his family. Wolf and Werner, who both went into the same profession, couldn't be any more different: the one is worldly and an experienced man-about-town; the other a small bourgeois.
