Couples who were passionate before marriage may not be so after marriage. When the daily necessities replaced the love, the cracks in life gradually exposed: Jason (Jason Bateman) and his wife Cynthia (Kristen Bell) considered divorce because of infertility, Joey (Jon Favreau) and Lucy had no interest in each other's bodies, and Dave (Vince Vaughn) and Ronnie were upset by the pressure of the house and children all day long. Seeing that the once enviable marriage was about to collapse, Jason and his wife decided to make a last-ditch effort. They tried their best to come up with a vacation therapy and persuaded several pairs of happy enemies to go to a tropical island for a second honeymoon. The exotic blue sea and blue sky seem to have restored the passion of these middle-aged couples, but the rigid courses offered by the resort owner Marcel (Jean Reno) have left them puzzled: Can the shocking male yoga, couples massage, and swimming with sharks really awaken the emotions of these couples and save their marriages?
