Two best friends—one unlucky-in-love divorcé (Robin Williams) and the other a fun-loving bachelor (John Travolta)—have their lives turned upside down when they're unexpectedly charged with the care of six-year-old twins while on the verge of the biggest business deal of their lives. The not-so-kidsavvy bachelors stumble in their efforts to take care of the twins (newcomers Ella Bleu Travolta and Conner Rayburn), leading to one debacle after another, and perhaps to a new-found understanding of what's really important in life.
