They make their decision to go to sturdy wings, which has volunteers helping with the needs of young youth. In this movie they are both paired up with their own kids (little). One kid is bad, and hard to control, and the other kid is reserved, shy, and in his own reality world. All four of them have to get along and stay out of trouble in order for the men to stay out of jail. Stuff happens along the way, like the camping trip, and the convenient store car theft by one of the littles (as the kids are referred to).
They all have to overcome some obstacles in order to save their home lives, and relationships. The men learn a lot about themselves along the way. The big's and the little's relationship starts off rocky, but in the end they make a great team and help one another out. The guy who lost his girlfriend does eventually get her back, but not without jumping though many hoops to satisfy her needs. Critics rave about this comedic movie.
