Irony abounds in this French comedy that tells the tale of an unsophisticated, rather dim-bulbed country lad who follows the advice of a former French freedom fighter and tries to change himself into a hero of the recently ended French Resistance. Poor Albert is no stranger to deceit. For his first 12-years, his mother led him to believe that his father was a war hero. He is devastated to learn that his father really died of alcoholism. During the war, Albert does all he can to avoid fighting for the Resistance, even though the Nazis control his village. He marries and moves in with his wife's family, innocent of the fact that the whole time he is there, they are concealing downed British fliers. The night their town is freed, Albert leaves for Paris where he meets Dionnet, "The Captain," a bona-fide Resistance hero. It is he, who teaches Albert how to successfully change his identity. After much practice and memorization, Albert finally has a new identity and goes to work as a secretary for Mr. Jo, a former double agent. Albert stays in a boarding house, where a resident prostitute teaches him about lovemaking. Meanwhile, Albert becomes recognized as a courageous patriot, a role he manages to sustain only a little while before it all falls apart and the painful truth is finally revealed.
