Nick (Jim Broadbent) and Meg Burrows (Lindsay Duncan) are a married academic couple from Birmingham advancing in age and tension. To mark their 30th wedding anniversary, the two embark on a trip to the place they honeymooned three decades before: Paris, France. Hoping to rejuvenate their marriage, the couple arrives in Paris only for things not to go as planned. Eventually, the two bump into Morgan (Jeff Goldblum), with whom Nick went to university and who is now a successful writer, and attend a dinner party of his that ultimately opens up a new view of life and love for the aging couple.
