SPOILERS AHEAD
What is after all the structure of this movie? It's really not that hard to realize, after a few viewings:
Diane Selwyn has came from Deep River, Ontario. She dreamt of becoming a big movie star in the city dreams come true - Hollywood. But the producers never thought too much of her, and she never got the main roles. In one movie, she met Camilla Rhodes, which took the main role she was pursuing, and pitifully casted Diane as a supporting actress. Diane fell in love with Camilla, and they started a relationship. But it's a hard life - Camilla begins a relationship with Adam Kesher, the movie's director. This is too much for Diane, and she hires a killer to assassinate Camilla. She then stays at home and falls asleep.
She now dreams she is called Betty Elms and she is starting all over again. Everything is right in this dream world: Betty has a magnificent house all for herself and everybody is nice to her, the director Adam Kesher is having a real bad time, her audition is a success and most of all, the woman that resembles the real-life Camilla, and tries to remember who she was before the accident she had in Mulholland Drive, falls in love with her. But this dream will end. And at the club silencio, the truth will be revealed, and when the blue key opens the blue box, Betty will become Diane again.

At her home, Diane finds the blue key that the killer said he would leave when he finished the job. Therefore, Camilla is dead. This is too much for Diane, which shoots herself.
David Lynch has created his greatest masterpiece right here, a wittily edited movie which makes us dive into the realms of our dreams and our minds. The story above is just the starting point to see this movie and analysing all the more obscure aspects once more like the real meaning of the club silencio, the importance of the cowboy, the old lady that appears at Betty's door, and that blue box. David Lynch gave a few useful tips, but the best way to solve this is by means of dialogue with other passionated viewers of the movie. This is a magnificent achievement in aspects, and I must say that after this, Naomi Watts can't pass unnoticed again - she gives one of the best character transformations ever, sometimes you'll wonder if it's really the same person.
10 out of 10, this movie deserves no less. A work of genius.
