Eugen, Wrigley, Bäschteli and Eduard are four young rascals who spend their time playing pranks upon the citizens of 1960’s Berne. Incidents involving an antique helmet and a leaky boat get them into hot water with their parents, and Eugen and Wrigley face cruel and unusual punishment: no scouts’ camp, and banishment to boarding school! Our two heroes hightail it in order to look for Fritzli Bühler, the erstwhile King of Rascals, whose legendary pranks are still the talk of Berne’s cobbled streets. Their odyssey takes them to the Italian-speaking part of Switzerland, where they are joined by Bäschteli and Eduard, and by bicycle across the Alps to Zurich. Pursued by worried parents, wrathful peasants and any number of policemen they travel all over Switzerland. While their parents and the authorities launch a nationwide search, the four boys strengthen their friendship and enter into a bond to rival that of the Swiss Confederation: “We shall stand united as a people of brats…” By the end of their adventures the four rascals will be famous – and much more.
