Sheila Levine Is Dead and Living in New York (1975)

Sheila Levine is a Jewish-American princess and a native of Harrisburg, Pennsylvania. An innovative, bright, but painfully introverted individual, she comes to New York City with her mother and father to take an apartment with a nightclub-hopping roommate. Persuaded to go to a nightclub one night, she meets a doctor named Sam Stoneman who is on the hunt for a one-night stand. Sheila develops an intense attraction towards Sam who seemingly is attracted to Sheila's desperately flirtatious roommate. She returns to Harrisburg for a time and comes back to win the heart of Sam only to discover that he has been conned into an engagement with her ex-roommate. Meanwhile, stalwart Sheila quickly climbs the ladder at her job as a "office-singer/typist" for a record company.
