Plot
Annie Burroughs is a wild 19-year-old who has just dropped out of college. Fearing to face her father, she packs her stuff and moves in with her older sister Marsha, who runs her own gallery in Los Angeles. Marsha is in a relationship with David Mitchell, a 31-year-old doctor who dreams of having his own private practice. Although they are very happy together, David isn't glad Marsha is spending so much time on work. Meanwhile, Annie immediately settles in the big city, landing a job as a receptionist at David's clinic. Although at first it is innocent and playful, Annie and David start flirting with each other.
A subplot focuses on the relationship between Annie and her father Tom. When she was still a child, Annie witnessed the death of her mother. She was crossing the street when a car suddenly drove toward her. Her mother, trying to save her, ran on the street and pushed Annie away, after which she was fatally hit by the car herself. Ever since, she and Tom do not get along well. Annie feels that her father blames her for her mother's death.
Annie once wanted to become a painter, just like her mother, but after her death she became isolated and gave up that dream. One night, David fails to save the life of his patient Billy, who has committed suicide. Annie witnesses his death and is reminded of her own mother. Both feeling very emotional, Annie and David end up kissing each other. The next day, Annie feels guilty, but David assures her it was only an innocent kiss. One night, Tom is throwing a family party. Annie gives him a self-made painting, but the style reminds him too much of her mother's, which upsets him. They end up getting into a fight, after which Annie leaves.
