France in the 1960s: Little Nick is supposed to write an essay at school about what he wants to be when he grows up. But he can't find an answer because, after all, everything is supposed to stay the same: Nick's father earns the money while his mother takes care of the household and looks after her son with much love. Nick's ideal world is shaken, however, when his father and mother suddenly stop fighting. Instead of being happy about this, Nick suspects that a little brother is on the way "Little Nick" is based on the famous novel by René Goscinny and Jean-Jacques Sempé.
