When Tim and Joshua meet up 15 years after college, these old friends who couldn't have been more alike realize that a few things have changed. Well, scratch that. Joshua hasn't changed one bit. He is as irresponsible carefree and immature live for the moment as he always was. Tim, on the other hand, is married and has a family. If that was the end of it, things would probably be just fine, but far more disturbing (to Joshua) is that Tim has turned into a green, environmentally-conscience, change-agent (Tim's words) i.e. a Tree-Hugging, Dirt-Eating Hippy (Joshua's words). Can these two find some common ground to co-exist peacefully? Or, more importantly, can Tim turn Joshua "green" in the short time this freeloader is his house guest? (Which may actually be a lot longer than Tim thinks...)
