In this family comedy, single parents Frank (Dennis Quaid) and Helen (Rene Russo) tie the knot... but with 18 children between them trying to sabotage the marriage, they discover that marriages -- and families -- canít be built in a day.
When Frank Beardsley (DENNIS QUAID), a widower with eight children, runs into his high school sweetheart, Helen North (RENE RUSSO), itís as if thirty years never passed! Helen, also a widow with ten kids of her own that include the six she and her husband adopted, feels the attraction as well. Itís no wonder they rush into marriage without telling their kids. True love can conquer all -- right?
Unfortunately for Frank and Helen, the families donít mesh quite as easily as the newlyweds had hoped. They probably should have seen the culture clash coming: the disciplined Beardsleys run things by the book; for the energetic and vivacious Norths, there is no book. Helenís kids arenít pleased about moving and sharing rooms with a bunch of uptight strangers. Frankís children have nothing in common with the unruly Norths. Since both sets of kids arenít happy, they devise a plan to undermine the marriage and team up to plot the breakup. East meets west as the two families find a way to work together -- in order to separate!
Just when it appears that the kids have succeeded, they realize they like each other despite their differences -- they donít want their families to split up! Can they save Frank and Helenís marriage after they so brilliantly split them up? Itís up to Frank and Helen...
