She lands in LA and is loaned a luxury Audi for social media promotion. She moves into the Ellis Building, a mostly empty high-rise on an inactive fault line. At her second audition, she meets a brunette actress named Emily Bryant. Emily is anxious about an expiring parking meter. Mia offers to feed it and takes Emily’s keys and wallet. When Mia returns, Emily has vanished completely. Outside, a man named Nick helps pay the meter. Mia and Nick exchange numbers. Mia later breaks into Emily’s car and finds her rental agreement, phone number, and address. A text arrives from Emily requesting the belongings.

The next morning, the laptop, phone, and Mia’s notes are gone. A warning note replaces them. CCTV shows that Michelle, Mia’s supposed assistant, is the woman from the audition.

Mia stages a car accident to explain her injuries. She deletes her recording, returns Nick’s gun, and flies back to London. Three months later, Mia wins the BAFTA. Emily’s body is found in a weighted suitcase in Lake Hollywood. Marla’s body is never found. Eighteen months later, Mia spots Marla on screen under a new name.
