In Star Trek: Insurrection, the secretly relocated inhabitants live on the Ba'ku planet.
The Ba'ku are a small community living on a planet whose rings emit metaphasic radiation. This radiation has powerful rejuvenating effects, making the world extremely valuable to outsiders who want to exploit its properties.
Admiral Matthew Dougherty, the Son'a, and Federation collaborators plan to remove the Ba'ku from their home so the radiation can be harvested. They conceal the operation with a sophisticated holographic system, but Lieutenant Commander Data discovers the hidden settlement and exposes the scheme.
Captain Jean-Luc Picard refuses to support the forced relocation. The conflict raises questions about whether Federation principles can be abandoned for a medical or economic benefit. The Ba'ku planet is often discussed alongside the Son'a, who are descendants of the Ba'ku and seek the radiation because it could restore their damaged bodies. The film was released in 1998.
