Camilla left Diane for the director of her recent movie, and Diane is heartbroken to the point of devastation. We learn through flashbacks that she was in a relationship with the brunette who was named Rita in the first half - though here, her name is Camilla and she’s a rather successful actress. Diane is depressed, unkempt, and near a mental break.
The second half of the movie finds Watts playing another struggling actress, but this time, her name isn’t Betty, it’s Diane Selwyn, and she lives in Diane’s apartment from the first half of the film.
