Seven years marks a point in many marriages when couples find themselves restless and dissatisfied; and some even wonder what it would be like if they had picked a different spouse. Seven Year Switch will follow the journey of four couples who have hit a breaking point in their marriage. Each of the couples, who have not had children as of yet, will participate in an innovative experiment of switch therapy, in which they swap partners and partake in experimental marriages. Two relationship experts will help guide the couples through the switch therapy process, as they adjust to living with an experimental spouse. Will their temporary partners be able to fill the void they've been yearning for, or will they discover that the grass isn't always greener? At the end of the month-long experiment, each of the married couples will reunite and make the decision: to either part ways and divorce, or reaffirm their commitment and renew their vows.
