Pastor Calvin Roberson and Dr. Jessica Griffin invite 16 singles to have their honeymoon before the wedding. With only two days to couple up and start their journey toward marriage, the singles must rely on instant chemistry to find their match.

The couples spend time getting to know each other and for some, the instant chemistry deepens, while others struggle to form a connection. One scorned single returns to the island to break up a happy couple in hopes of a second chance.

The couples are asked to talk about their pasts and for one person, the stress of this accelerated process leads to a major breakdown. A surprise visitor arrives on the island, which may change the course of one couple's relationship forever.

The guys confess to Jona they are worried that Brandin is leading him on, and 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. 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 faces yet another roadblock on their road to marriage.

Pastor Cal surprises some with a visit from family, but the stress of meeting the potential in-laws may be too much for one couple. When a couple reveals they are living together, it's an uphill battle to get their parents' permission for marriage.

Four couples have worked with Pastor Cal and Dr. Jessica to grow their instant attraction into love. After three weeks of honeymooning, each individual must decide if they're ready to commit to an engagement or break up and part ways forever.
