Michael Clayton (George Clooney) handles all of the dirty work for a major New York law firm, arranging top-flight legal services and skirting through loopholes for ethically questionable clients. But when a fellow "fixer" decides to turn on the very firm they were hired to clean up for, Clayton finds himself at the center of a conspiratorial maelstrom. Once an ambitious D.A., Clayton is now a shell of his former dynamic self, thanks to a divorce, an unfortunate business venture, and astronomical debt. Though he longs to leave the cutthroat, ethically dubious world of corporate law behind, Clayton's poor financial situation and devotion to firm head Marty Bach (Sydney Pollack) leave him little choice but to remain on the job and tough it out. Meanwhile, litigator Karen Crowder (Tilda Swinton) finds her entire company's future hinging on the outcome of a multi-billion-dollar settlement overseen by Clayton's friend, star lawyer Arthur Edens (Tom Wilkinson). When Edens snaps and decides to blow the whistle on the questionable case, sabotaging the defense, Clayton must decide between his loyalty and his conscience.
