Opposites attract when, during their college days, Katie Morosky, a politically active Jew, meets Hubbell Gardine, a feckless WASP. Years later, in the wake of World War II, they meet again and, despite their obvious differences, marry. Hubbell wants to be a screenwriter, so the two move to California despite Katie's objections. They prosper there, but as the Hollywood blacklist looms, Katie's activism threatens her husband's reputation.
