1861: The war that's been brewing for a decade has exploded, pitting North against South. Fearing that England will support the Confederate cause, President Lincoln sends Charles Francis Adams, son of John Quincy Adams, to London. But when Charles arrives, accompanied by his son Henry, he discovers that the English are already building warships for the South. As Charles embarks on a high-stakes game of espionage and diplomacy, Henry reconnects with his college friend Baxter Sams, a Southerner who has fallen in love with Englishwoman Julia Birch. Julia's family reviles Americans, leaving Baxter torn between his love for Julia, his friendship with Henry, and his obligations to his own family, who entreat him to run medical supplies across the blockade to help the Confederacy. As tensions mount, irrevocable choices are made-igniting a moment when history could have changed forever.
