Summary for the movie
Mr. Topaze ('Peter Sellers') is an unassuming school teacher in an unassuming small French town who is honest to a fault. He is fired when he refuses to give a passing grade to a bad student, the grandson of a wealthy baroness. Castel Benac (), a government official who runs a crooked financial business on the side, is persuaded by his mistress, Suzy (), a musical comedy actress, to hire Mr. Topaze as the front man for his business. Gradually, Topaze becomes a rapacious financier who sacrifices his honesty for success and, in a final stroke of business bravado, fires Benac and acquires Suzy in the deal. An old friend and colleague, Tamise () questions him and tells Topaze that if what he now says and practices indicates there are no more honest men.
