A summer's day in a Berlin suburb. Frank, a loud-mouthed hallodrider, is constantly running into nothing. Karla, a depressive sleeping beauty, is constantly falling over. No wonder Frank keeps tripping over Karla. Ex-punk and hippie buckle? Why not, think Ratzo and Izzy, two drunks for whom life is one big quiz show. However, standing in the way of the health food store owner is Harry, the last person still running a "Nicaragua Group". Meanwhile, journalist Robbie is on the hunt for a Nobel Prize winner who has gone into hiding. And two tourists from the Caucasus are looking for "Dschumbrilla". So everyone is on the lookout and finds something different.
