A newlywed couple turns to a scientist for help having a baby and find themselves at the center of a genetic puzzle with far reaching implications and an ethically ambiguous solution.

When a workaholic young executive (Kristen Bell), is left at the altar, she ends up on her Caribbean honeymoon cruise with the last person she ever expected: her estranged and equally workaholic father (Kelsey Grammer). The two depart as strangers, but over the course of a few hilarious adventures, a couple of umbrella-clad cocktails and a whole lot of soul-searching, they return with a renewed appreciation for family and life.
