Marie (Juliet Binoche) breaks it off with Mitch (Dane Cook) during the family reunion and leaves.
She calls Dan (Steve Carell) and the two of them meet up at the bowling alley where they are eventually discovered by the entire family.
Marie leaves and at his daughter's request, Dan goes after her (along with his daughters) and they find her at the gym back home in the city - She is obviously thrilled to see them all.
The movie ends and during the credits we see the two of them geting married at his folk's house.
(Mitch is there with the girl the family set Dan up with earlier in the film)
