Enormous Changes at the Last Minute is a compilation film of three feminist yet disheartening stories of failed relationships. The first story features Virginia (Ellen Barkin) whose deadbeat husband has just left her and their three children. As a result, she is forced to go on welfare. She begins an affair with a now-married old flame, and struggles to keep sanity and humor alive against high odds. In the next vignette, Faith (Lynn Milgrim) visits her still-hip, literary parents in their retirement home to let them know that she and her husband have separated -- and she gets some shocking news in return from her father. In the last story, a social worker and a cabbie (Kevin Bacon) start an affair on a feeble pretext for mutual attraction, and when the social worker gets pregnant, her one-sided decisions on the matter have unexpected effects.
