The Apprentice(1971)

Original title: Fleur Bleue

In Montréal, Jean-Pierre is fired on the set of a TV commercial where he's an apprentice technician. He's penniless, behind on his rent, with a thin resume and no college units. He has a fiancée, Michelle, but his head is turned by a free-spirited model, from the U.S., who saw him being fired and comes to his flat to apologize. She's Elizabeth, a combination of feckless innocence and sexual freedom. Jean-Pierre borrows money from his outlaw friend, Dock, and buys clothes to impress Elizabeth. Soon he's sleeping with her, and he pulls a theft with Dock to get money to take her to Acapulco. Michelle tries to bring him back to her orbit. Is there a way out for Jean-Pierre?
