Widower Jacob, reputedly the best Dutch police detective, has been preparing his son 'Nono' since age three to succeed him, although the cute, smart brat seems absentminded and accident-prone. Having clumsily caused a family scandal at a cousin's bar mitzvah -Jewish passage to manhood rite, at age 13- shortly before his own, Nono is ordered to spend time with an ancient uncle, dreaded, dreary educational professor Sjmoel but discovers on the train that's a cover story for his real coming of age. He's to devise and execute his own secret mission under the guidance of daredevil criminal mastermind Felix, never arrested except by Jacob. He chooses to investigate Lola, the French singer idol of Jacob's in-living 'assistant' Gaby, and the 'curse' of his own late mother Zuhara.—KGF Vissers
