In 1951 Hollywood, Eddie Mannix is head of production at Capitol Pictures. His duties as the studio "fixer" find him covering up for its scandalous stars and fending off twin gossip columnists Thora and Thessaly Thacker. All the while, he is weighing a generous job offer from the Lockheed Corporation. When unmarried synchronized swimmer-turned-actress DeeAnna Moran becomes pregnant, Mannix arranges for DeeAnna to place her baby in foster care then discreetly adopt it, preserving her career.
Baird Whitlock, the talented but dim-witted star of the studio's newest major production Hail, Caesar! A Tale of the Christ, is drugged and abducted. He awakens at a meeting of "The Future," a group of blacklisted Communist screenwriters, and is easily won over to their cause. The Future send a ransom note demanding $100,000 for Baird's return, which Mannix procures from the studio. He convinces Thora to withhold a story in exchange for information on singing Western film star Hobie Doyle.
Hobie has been hopelessly miscast in a sophisticated comedy of manners and, despite the efforts of director Laurence Laurentz, cannot overcome his thick Western American accent. When Laurentz requests Hobie's removal, Mannix convinces him to continue his coaching. Hobie admits to Mannix his unease about the role, but Mannix reassures him and confides in him about Baird's kidnapping.
That evening, Hobie attends the premiere of his latest Western with starlet Carlotta Valdez, as arranged by Mannix. The pair are accosted by the Thacker sisters, but Hobie spots the briefcase of ransom money, carried by musical star Burt Gurney. Mannix and DeeAnna meet with surety agent Joseph Silverman, a trusted scapegoat for the studio, who agrees to foster DeeAnna's child. His dependability proves immensely attractive to DeeAnna. Hobie follows Burt to The Future's beach house but finds only Baird inside. The Future have taken Burt to rendezvous with a Soviet submarine and defect to the USSR but lose the briefcase in the ocean. Hobie returns Baird to the studio as police arrive to arrest the group.
Baird spouts his newfound Communist beliefs to Mannix, who slaps Baird and orders him to "go out and be a star" and finish Hail, Caesar! The next morning, Mannix learns that DeeAnna has married Silverman. Mannix declines Lockheed's offer, remaining at Capitol Pictures. Thora tells him that her column will reveal Baird won his role in an earlier picture by having sex with Laurentz, but Mannix threatens to ruin her reputation by publicly naming her source as Burt, a Communist and recent Soviet defector. Thora backs down from running the story and Mannix moves on, confident in his role in life.
