Aspiring actress Louise Muban attends the prestigious Paris School of Drama during the day and works at a dreary factory assembling gas meters at night. She daydreams and "acts" her way through life, and her fellow students at school begin to suspect her stories are just that - fabrications. After Louise begins to weave an actual meeting with a debonair playboy into a fantasy of club dates and romance, her classmate Nana discovers the lie when she too meets the playboy. Nana sets a trap for Louise, and the result is an end to one fantasy and the realization of another.
