Thriller set in the murky world of corporate law. Michael Clayton (George Clooney) is an in-house 'fixer' at one of the largest corporate law firms in New York. A former criminal prosecutor, Clayton takes care of his employer's dirtiest work at the behest of the firm's co-founder Marty Bach (Sydney Pollack), to whom Clayton feels a deep loyalty. He arranges top-flight legal services and skirts through loopholes for their ethically questionable clients. Though burned out, disillusioned and hardly content with his job as a fixer, his messy private life has left him inextricably tied to the firm. 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 defence, Clayton finds himself in the centre of a conspiratorial maelstrom where he must decide between his loyalty and his conscience.
