Eight couples whose relationships have reached breaking point are whisked off to a tropical Mexican resort, where they will find out whether their current squeezes are really right for them. Expert-led behaviour workshops, challenges, and sex therapy sessions aim to give each participant a deeper understanding of themselves, and each other. However, on arriving at the resort, each couple's relationship is put "on a break", and they are forced to swap partners every 48 hours, meaning the temptation to play away might prove too much for some.
