Quatermass and the Pit - Season 1 - Eps 6: Hob
Despite his warnings, the media event occurs, and the power cables that string into the craft fully activate it for the first time. Glowing and humming like a living thing, it starts drawing upon this energy source and awakening the ancient racial programming. Those people of London in whom the alien admixture remains strong fall under the ship's influence; they merge into a group mind and begin a telekinetic mass murder of those without the alien genes, an 'ethnic cleansing' of those that the alien race mind considers impure and weak.
