The Konianski family consists of:
Simon, 35 years old, an eternal teenager, who has recently been dumped by the woman of his dreams, a goy dancer.
Ernest, his father, obliged to take him in provisionally, who quickly turns Simon's life into a living nightmare.
Hadrien, Simon's son, a little boy passionate about the awful memories of his grandfather, a former concentration camp internee.
Maurice, the elderly, paranoid uncle and Aunt Mala, who never hesitates to speak her mind.
When Ernest disappears, this little gang set out on an expedition that risks being as nutty as they are.
