Don’t Dress for Dinner follows Jacqueline and Bernard, a happily married couple—or so it seems. When Jacqueline makes plans to visit her mother for a few days, Bernard prepares to spend some time with his new mistress. An old bachelor pal, Robert, announces his return from Hong Kong, allowing Bernard to believe he's found the perfect alibi, until Jacqueline learns of Robert’s arrival and changes her travel plans. Throw in a Cordon Bleu-level chef and two women named Suzy and voila! Dinner becomes a high-speed farce.
