Five couples have only two weeks to plan their weddings, celebrate their final days of being single, and reveal to their family and friends that they are getting married to a stranger! And when the time finally comes to tie the knot, will one groom be left at the alter when his bride-to-be gets a call from her ex-boyfriend asking her not to go through with it?

After getting married at first sight, the four couples are whisked away to Costa Rica for their honeymoons. While enjoying grand adventures in paradise, they discover that their new spouses might not be as perfect as they initially thought.
