What to Watch

10 p.m. on PBS

The glittering lure of gold is at the heart of a modern struggle in a 2,000- year-old Romanian village, where a Canadian company wants to excavate an open-pit gold mine at a spot thought to have been first discovered by the ancient Romans. On one side of the struggle are long-held rural traditions, environmental concerns and landowners trying to protect their homes, which would be lost in the excavation efforts. But mining advocates point to the economic need for the minerals -- not to mention the demand for jobs.
