The unbeatable combination of star Fernandel and director Henri Verneuil strikes again with Le Fruit Defendu (Forbidden Fruit). Fernandel plays a rural doctor, trapped in a dull, uneventful marriage. During a visit to the city, the doctor falls for a young lady (Francoise Arnoul) of very loose morals. Unwilling to relinquish this affair upon returning home, the doc works out a clever scheme whereby he can install the girl in his own home without arousing the suspicions of his wife (Claude Nollier) . How he does this, and how he's finally caught, is handled in a hilarious but scrupulously tasteful fashion.
