Returning home after years away, a reunion with old friends leads to newly-retired Kiwis Lee and Tony Straw setting off on a journey to Central Europe. The plan is to visit those friends in Berlin, but New Zealanders don't travel such long distances for just a single destination. So the journey grows. And grows. Their meanderings take them through San Francisco to Germany and several countries sharing a border with Germany, not ignoring tourist attractions but leaning more towards lesser-known diversions. Setbacks happen, but often these lead to new adventures that turn out to be every bit as enjoyable as those they had originally planned. Come along with Tony and Lee, and occasionally too with Tony's son, Martin, for a fun ride, humorously told, filled with good beer, good - or at times mediocre - food, as well as castles, rivers, mountains, monuments and a sometimes stroppy GPS called Gretel.
