Overall, I would give this movie a B- or B.
There is very brief nudity, like a minute total, and there is quite some language used.
Basically, this guy Doug is getting married, so 3 others take him to Las Vegas for a Bachelor party. The end up getting very drunk and lose there friend Doug. The take a day to try to find him, just going all over the place to find him. It is Doug's wedding day, and they couldn't find him. In the end, they find him and get him to his wedding. (I am not telling how they found him.. Ruins the whole movie.)
Between this and my other Movie Review of Zombieland, I chose Zombieland over this movie only because of the funniness and plot.
