For Marion it's her fifth driving test, for the examiner it's his last day before retirement. They've only driven a few minutes before they hit a pedestrian who dies instantly. They now have twenty minutes to find an alibi and pretend it's absolutely nothing to do with them.
In this WW2 epic comedy – in the vein of “La Grande Vadrouille” – our two heroes, Max and Léon, two lazy and partier pals, will try by all possible means to avoid going in the battle zone… This will lead the duo to demented and wild adventures.
