Miles Massey (George Clooney) is an exceptional divorce lawyer who specializes in saving cheating husbands from having to pay expensive settlements. Unchallenged, he wearies of his life -- until he meets the cunning Marylin Rexroth (Catherine Zeta-Jones). When Massey's representation of her husband in court denies her any divorce compensation, Marylin vows to get revenge, enlisting the help of an oil baron (Billy Bob Thornton), and the two vie for the advantage in a flirtatious duel of wits.
