I feel like telling you what this movie is about in one sentence would ruin the whole point of the movie.
Just watch it.
The central figure in this hallucinatory film is Fred Madison (Bill Pullman), a saxophonist whose marriage to Renee Madison (Patricia Arquette) is full of unspoken tension. Those friction run even higher when a bunch of anonymous video tapes are found on their doorstep. Something or someone is spying on the house and its occupants. On one of those tapes, we see how Fred murders his wife, is condemned to death and ends up on death row..
QUALITIES: one of those movies you have to watch a few times to get, but when you do, it's the best experience ever, David Lynch
