Kay (Meryl Streep) and Arnold (Tommy Lee Jones) are a devoted couple, but decades of marriage have left Kay wanting to spice things up and reconnect with her husband. When she hears of a renowned couple’s specialist (Steve Carell) in the small town of Great Hope Springs, she attempts to persuade her skeptical husband, a steadfast man of routine, to get on a plane for a week of marriage therapy. Just convincing the stubborn Arnold to go on the retreat is hard enough – the real challenge for both of them comes as they shed their bedroom hang-ups and try to re-ignite the spark that caused them to fall for each other in the first place.
