060.03 Doctor Who: The Crucible of Terror part three

The invasion is no longer a distant threat — it is here. In Part Three of The Crucible of Terror, the Doctor faces an impossible dilemma as Earth stands on the brink of annihilation. A vast alien warship looms overhead, a merciless mercenary named Drax demands the surrender of the Crucible, and humanity’s leaders are paralysed by fear, mistrust, and jurisdictional conflict. As UNIT and the U.S. military clash over authority, the truth about the Crucible is finally revealed — along with the terrifying cost of using it. With time running out, the Doctor must gamble everything on an untested plan, while Kevin Vasavious is forced into a role he never wanted, and Kathy confronts the horrors of her past.
