Serge Pilardosse has just turned 60 and is about to retire from his job in a slaughterhouse. He has always worked from the age of sixteen, never been on sick leave. So, how will this man fill his days? He does not like reading, doing odd jobs about the house is not his cup of tea, shopping is not his passion, to make matters worse, his wife Catherine, who still works in a supermarket, notices that her husband will not get full retirement benefits since some of his former employers failed to do the requisite paperwork. So off goes Serge, riding his old Munch "Mammut" bike, in search of the missing documents.
