In this 1949 black-and-white classic, which won Joseph L. Mankiewicz an Academy Award for Best Director, three married women (Jeanne Crain, Linda Darnell and Ann Sothern) vacationing on the Hudson suddenly find themselves on the receiving end of a disturbing missive: One of their husbands has broken his nuptial vows and cheated. But whose? The answer is revealed as each woman excavates the ruins of her marriage. Kirk Douglas costars.
