It’s Hollywood, 1958. Small town beauty queen and devout Baptist Marla Mabrey (Collins), under contract to the infamous Howard Hughes (Beatty), arrives in Los Angeles. At the airport, she meets her personal driver Frank Forbes (Ehrenreich), only two weeks on the job and also from a religiously conservative background.
Their instant attraction not only puts their religious convictions to the test, but also defies Hughes’ #1 rule: no employee is allowed to have an intimate relationship with a contract actress. But Hughes’ absurd behavior intersects with Marla and Frank in very separate and unexpected ways, and as they are drawn deeper into his bizarre world, their values are challenged and their lives are changed.
