The jitterbug scene, upon which is superimposed a resplendent Diane and the happy couple, is replete with evocations of professional glory. It's like the Oscars: dazzling lights, applause. This is Diane's reverie, which fades as we vicariously descend into her bed. Red sheets smother Diane, who breathes laboriously because her existence is painful.

The resting Diane dreams she is the aspiring actress "Betty", who assists amnesiac car-crash victim "Rita" to discover her true identity. Everything which ingenue "Betty" experiences is a distorted version of recent events in Diane's life. "Betty" aces an audition, falls in love with "Rita", and is admired by director Kesher. But suicidal thoughts permeate Diane's dream. At Silencio "Betty's" existence and performance are exposed as beautiful illusions which mask real-life sorrows. The blue box is a symbolic portal that separates the self Diane is and the dream-self she wishes she were ("Betty"). Its opening returns Diane to brutal reality.

"Rita" is really Camilla, a star who seduced Kesher whilst having a sordid affair with Diane, who is a struggling wannabe. Diane's ambiguous feelings about Camilla (love and jealousy) explain why, in "Betty's" world, "Rita" was both injured and rescued. Diane also justified her professional failure by imagining a director bullied into making his casting decision. Diane sits in her robe remembering how she arranged Camilla's murder.
The reappearance of the ashtray indicates a memory. The assassin announces the murder's completion by leaving a blue key at Diane's apartment where her delirium ensues. Diane remembers Camilla's party, at the location of "Rita's" accident, where the guests, who treat Diane contemptuously, are people Diane imagined as characters in "Betty's" world. Ruth is dead, resurrected only in Diane's dreams as a Hollywood paradigm. The Winkies bum, a symbol of self-loathing and deterioration, haunts Diane, along with the happy couple who represent lost innocence, and Diane kills herself.
