Lifelong friends in their old age decide to give their lives one more big spin. When one, a lifelong bachelor, prepares to finally get married, there’s a chance to have some fun. And where? Nowhere other than Las Vegas. Originally all from Brooklyn, life has taken them each somewhere else. One of them is alone in Brooklyn, another is with his wife in Florida, and a third lives in Jersey with his son. When the fourth, a rich lawyer in Malibu, calls them, he pulls them from their sleepy lives. He announces that he's finally asked his half-his-age girlfriend to marry him. It is decided – they'll meet in Las Vegas and have a proper bachelor party. When they arrive, they find that this isn't the Vegas they once knew... The four old friends know full well, however, why they came to this old Sin City and set out to conquer it anew.
