Mulholland Drive

A dark-haired woman is the sole survivor of a car crash on Mulholland Drive, a winding road high in the Hollywood Hills. Injured and dazed, she makes her way down into Los Angeles by foot and sneaks into an apartment. Later that morning, an aspiring actress named Betty Elms arrives at the apartment, which is normally occupied by her Aunt Ruth. Betty is startled to find the woman, who has amnesia and calls herself "Rita" after seeing a poster for the film Gilda starring Rita Hayworth. To help the woman remember her identity, Betty looks in Rita's purse, where she finds a large amount of money and an unusual blue key.
