Michael Clayton is a "fixer" for a prestigious New York City law firm, using his connections and knowledge of legal loopholes for the benefit of the firm's clients. One night, Michael leaves a poker game to attend to a client who struck a pedestrian with his vehicle in Westchester County. Driving home, Michael sees three horses standing at the top of a hill near some leafless trees. He stops, gets out of his car and approaches them. Behind him, a bomb detonates in his car.

Four days earlier, the firm dispatched Clayton to deal with a crisis that had been created when Arthur Edens, one of the firm's litigators, suffered a manic episode in the middle of a deposition. Edens had been conducting the defense of U-North, an agricultural conglomerate, in a six-year-long multi-billion-dollar class action lawsuit. The episode now threatens both the firm's reputation and the interests of its client. Michael bails Arthur out of jail in Milwaukee and learns Arthur is no longer taking his medication. Arthur escapes from his hotel room during the night and returns to New York.

Michael approaches Marty Bach, the firm's managing partner, requesting a loan to cover a failed investment in a restaurant Michael made with his ne'er-do-well brother, Timmy. Marty suggests Michael will be rewarded if he can get Arthur back on track but warns the firm will be finished if he fails.

Karen Crowder, U-North's general counsel, discovers that Arthur has a confidential U-North memo proving the company knew its weed killer was carcinogenic and caused the hundreds of deaths that sparked the lawsuit. U-North CEO Don Jeffries, whose signature is on the memo, puts Crowder in contact with two operatives, who follow Arthur and bug his apartment and phone.

Michael finds Arthur on a Manhattan street and confronts him about calls he made to Anna Kaiserson, the plaintiff being deposed during his episode, leading Arthur to realize that his calls are monitored. Nonetheless, Arthur calls Michael's son Henry who enthralls Arthur by telling him about a fantasy book, Realm & Conquest, and about the idea of the vision quest and the summoning of the hero to his quest. Arthur calls his own voicemail at the firm and says he will go public with the memo. Informed of this, Karen then calls in the operatives, who break into Arthur's apartment, murder him by means of lethal injection, and make it look like suicide by drug overdose.

Michael learns of Arthur's death but becomes suspicious when he discovers that U-North was planning a settlement just a few days before, and that Arthur had booked a flight to New York for Anna. He finds Anna and learns that she told no one of her conversations with Arthur, yet the firm somehow knew. With help from his brother Gene, a police officer, Michael breaks into Arthur's apartment, which had been sealed as a crime scene. Michael finds Arthur's dogeared copy of Realm & Conquest, which contains an illustration of a horse on a hill with barren trees, and several pages highlighted and annotated by Arthur. The book also contains a receipt from a photocopy shop, which Michael pockets. Two police officers soon arrive on a tip from the operatives, who have been trailing Michael. Michael is arrested, but Gene bails him out.

Taking the receipt to the copy shop, Michael discovers that Arthur ordered 3,000 bound copies of the confidential U-North memo which Michael takes, but one of the hit men also procures a copy. Marty offers Michael the money he requested as a bonus, but insists Michael also sign a three-year employment contract and a non-disclosure agreement covering his vast knowledge of the firm and its personnel. On the night of the poker game, the hit men rig Michael's car with a bomb and follow him through Westchester. After he gets out of the car to view the horses on the hill, it explodes. Michael hides with the help of his brother Timmy.

At a U-North board meeting, Karen proposes that the board approve a new settlement in the lawsuit. Michael confronts her in the foyer and goads her into offering him $10 million for his silence. When Karen agrees, Michael reveals that he is wearing a wire, with Gene and other NYPD detectives listening. As the police move in to confront Don and Karen, Michael gets into a cab and rides away.

The website's critical consensus reads: "Michael Clayton is one of the most sharply scripted films of 2007, with an engrossing premise and faultless acting. Director Tony Gilroy succeeds not only in capturing the audience's attention, but holding it until the credits roll."^[6] Metacritic assigned the film a weighted average score of 82 out of 100, based on 36 critics indicating "universal acclaim".^[7] Audiences surveyed by CinemaScore gave the film a B on an A+ to F scale.^[8]

Owen Gleiberman of Entertainment Weekly gave it an A, saying that it was "better than good, it just about restores your faith". Roger Ebert gave it a full four stars^[9] and Richard Roeper named it the best film of the year.^[10] It was also Richard Schickel's top film of 2007, and he called it "a morally alert, persuasively realistic and increasingly suspenseful melodrama, impeccably acted and handsomely staged by Tony Gilroy".^[11] Time wrote, "Michael Clayton is not an exercise in high-tension energy; you'll never confuse its eponymous protagonist with Jason Bourne. But it does have enough of a melodramatic pulse to keep you engaged in its story and, better than that, it is full of plausible characters who are capable of surprising—and surpassing—your expectations".^[11] Stanley Kauffmann of The New Republic wrote that "Gilroy's film is distinguished beyond its components by its purpose, its compassion, its interest—increasingly manifest—in the soul".^[12]
