Stanley and Ellie Banks (Tracy and Bennett) are an upper-middle-class Long Island couple with three children, the eldest of whom is 20-year-old daughter Kay (Taylor). Kay rather casually admits to her parents that she is engaged to marry one Buckley Dunstan (Don Taylor). The main plot involves the increasingly chaotic preparations for a fancy upscale wedding, and Stanley's increasing anxiety over the enormous bill that he, as the bride's father, has to pay. Eventually it becomes clear, however, that the real cause of Stanley's stress is separation anxiety over his only daughter growing up and leaving the nest.
One of the first grown-up roles for Elizabeth Taylor, who neatly averted Former Child Star syndrome and made a smooth transition into playing adult roles. Minnelli and the cast reunited a year later for a well-received sequel, Father's Little Dividend, which centers around Stanley's consternation at becoming a grandfather.
