Taggart: Crossing The Line

Preparations are underway for a new museum in the former mining community of Garsden on the outskirts of Glasgow. The museum will be on the site of a long disused coal mine, closed twenty five years before, just before the miners' strike. But when the shaft is opened up, two skeletons are found - a man and a woman in the same position as they died a quarter of a century earlier. Were they buried alive? Who are they? How did they get there - and were they murdered?
