Here is a comprehensive summary of the Wikipedia article about "Landman":

"Landman" is an engaging American neo-Western drama series, created by Taylor Sheridan and Christian Wallace, and notably inspired by Wallace's Boomtown podcast. Starring Academy Award winner Billy Bob Thornton as Tommy Norris, a shrewd landman for an oil company, the show premiered on November 17, 2024, on Paramount+. Set amidst the high-stakes oilfields of West Texas, the series delves into a massive boom that profoundly reshapes the region's climate, economy, and geopolitics, following the lives of "roughnecks and wildcat billionaires."

Thornton's character, Tommy Norris, navigates this cutthroat environment as an operations VP for M-Tex Oil, with early season tensions arising from an out-of-town lawyer investigating a fatal accident. The compelling ensemble cast includes Ali Larter, Demi Moore, and Jon Hamm (season 1), with Andy Garcia and Sam Elliott joining in later seasons. Its success led to quick renewals for a second season, which premiered on November 16, 2025, and a subsequent third season, cementing its place as a significant new drama.
