City Slickers II: The Legend of Curly's Gold

Mitch Robbins, played by Billy Crystal, is a man celebrating his 40th birthday when he finds a treasure map belonging to Curly Whitmire, a trail boss from the Old West. He joins forces with his friend Phil Berquist and his immature brother Glen to search for the hidden gold in the deserts of Arizona, led by a mysterious cowboy named Duke, who turns out to be Curly's identical twin brother. As they embark on their adventure, they encounter various mishaps, bandits, and unexpected allies, including the father of Curly and Duke, Lincoln Washburn. In the end, the group discovers the gold, but not in the form of bullion, as they had expected, and instead finds a bar of gold with a peculiar twist.
