 It is summertime but not holiday time for Jeannot, a mechanic in a small garage. Indeed, as his employer enjoys repeating sarcastically, he has already used all his days off for the year.

Strolling down the Paris streets basking in the sun, Jeannot starts discovering Paris ... and himself at the same time.
