Hail, Caesar! is the story of Eddie Mannix, tireless pursuer of the interests of fictional Capitol Pictures, circa 1951. He is the ultimate studio fixer and – since the studio is his world – the ultimate earthly one. There is no star scandal he cannot cover up, no studio misstep he cannot repair, no sin he cannot make right. His powers are tested, though, when production on the studio's most expensive picture ever – biblical epic Hail, Caesar! – is halted by the kidnapping of its star. The kidnappers are a mysterious gaggle seeking not just ransom but the destruction of everything Eddie Mannix lives for, and everything he lives by.
