Tilda Swinton gives the performance of a lifetime as Julia, a middle-aged alcoholic who totters around nightclubs on six-inch heels, and gets by on nickel-and-dime jobs sandwiched between shots of vodka and one-night stands. Julia is manipulative, unreliable and a compulsive liar, and when an opportunity presents itself to make a substantial amount of money, she jumps at the chance and commits a desperate act. As the repercussions spiral beyond her control, she is forced to make a choice between sacrifice and redemption.
