The film opens in a Wellington courtroom, where testimony prompts Barbara Leslie to flashback to the events that led to the trial. She and her sisters Anne, Evelyn, and Delia live in Christchurch, where most of the male residents, including their brother Kit and Barbara's new husband Mark, are preparing to leave for World War II duty. Delia announces her engagement to Phil "Shiner" Friskett, who is one of the city's few remaining bachelors, but word of Kit's death dampens the celebration. Repressed and judgmental spinster sister Anne disapproves of the upcoming nuptials, but Barbara defends Delia's decision.
