Set in 1950s Hollywood, Eddie Mannix is Capital Pictures’ head of physical production and is the studio fixer. His job is to maintain the clean reputation of the company and its stars. When Mannix is advised that studio star Baird Whitlock has disappeared after not showing up for work on the current production of “Hail Caesar, a Tale of Christ’s Life”, he initially believes Whitlock has been drinking. But, he receives a call from a group of communists who claim to have kidnapped the actor and want a ransom. When he is approached by an aviation company with an offer of a less-hectic, and rather lucrative, job, he must ultimately determine his true skills and passions.
