Caipiranha - Vorsicht, Bissiger Nachbar! plot
The Grabowski and Wolters families have always lived peacefully side by side, until a little thing changes that. Because Jürgen Grabowski (Thierry van Werveke) has nailed the garden door shut, Horst Wolters (Rainer Basedow) lets their apple tree fall down in the neighbour's garden. Wanting revenge, Jürgen decides to throw his wife's cat Monika (Katharina Thalbach) into the neighbor's yard so that it will eat Karin Wolters' (Christine Kaufmann) fish. As the bullying escalates, no one notices that the young daughter of one family has become pregnant at the hands of a son of the other family.
