They have only four months to convince Frank and Laura--who couldn't be less suited as mates--to call off their wedding. In desperation, Trevor and Janice implement a plan. Pretending to be in love, they double-date with Frank and Laura as a means to help the pair discover how wrong they are for each other.
But nothing Trevor and Janice do seems to matter. Even after attending a twelve-week premarital course with their friends, Frank and Laura remain stubbornly committed to their wedding plans. Throughout their time together as the "loving couple," Trevor and Janice grow close, and as the wedding day approaches, each secretly dreads ending their ruse.
As the big day arrives, will the wedding be on?
