Ma nuit chez Maud

A pious Catholic engineer in his early thirties, he lives by a strict moral code in order to rationalize his world, drowning himself in mathematics and the philosophy of Pascal. After spotting the delicate, blonde Françoise at Mass, he vows to make her his wife, although when he unwittingly spends the night at the apartment of the bold, brunette divorcée Maud, his rigid ethical standards are challenged.
