With multiple couples successfully married at first sight, Pastor Calvin Roberson and Dr. Jessica Griffin are inviting 16 singles to the only island where you can have your honeymoon before the wedding. But with only two days to couple up and start their journey towards marriage, these singles will have to rely on attraction and instant chemistry to find their match. Will all our singles remain on the island or will some be packing their bags to go home alone?

The couples spend time getting to know each other and for some, the instant chemistry deepens, while others struggle to form a connection. Each couple receives keys to a honeymoon suite and must decide to move in together, or go home alone. One scorned single returns to the island to break up a happy couple in hopes of a second chance.

To understand the psychology of relationships, the couples are asked to talk about their pasts. For one person, the stress of this accelerated process leads to a major breakdown. A surprise visitor arrives to the island, which may change the course of one couples’ relationship forever.

Halfway through their time on Honeymoon Island, the guys confess to Jona they are worried that Brandin is leading him on. Kimber and Shannon struggle to see eye to eye on a potential relationship deal breaker. After an intense group relay race, one couple’s ridiculous fight spins out of control.

The couples turn up the heat during intimacy exercises and while most take their relationship to the next level, Brandin gets a little too friendly with Tyler, causing one couple to go up in flames. Then, one couple leaves Honeymoon Island for good.

Pastor Cal leads the couples through spirituality exercises, forcing them to face their darkest fears; while one couple connects instantly on their shared beliefs, one couple faces yet another roadblock on their road to marriage.

The stress of meeting the potential in-laws may be too much for one couple to handle; after another couple reveals that they are currently living together, it is an uphill battle to get their parents' permission for marriage.

After three weeks of honeymooning, not all the couples are on the same page; each individual must decide for themselves if they are they ready to commit to an engagement, or if they should break up and part ways forever.
