Kevin Kline, Joan Allen and Sigourney Weaver turn in crystalline performances as two dysfunctional families learn to cope with the unyielding forces of nature -- human nature -- in this emotionally charged tale of suburban life in the '70s. When a self-centered husband's relationships with his wife and mistress grow cold, it takes a wife-swapping "key party" and a freak ice storm to clear the air and change their lives forever. Director Ang Lee offers a compelling look ata controversial era.
