Trying to discover what happened to Marsh, Quatermass contacts Inspector Lomax (John Longden), who had previously assisted him (see "The Quatermass Xperiment"). Lomax puts him in touch with Vincent Broadhead (Tom Chatto), a Member of Parliament, who has been trying to uncover the veil of secrecy surrounding Winnerden Flats and the organization and deliverance of massive quantities of material supplies and manpower without any real explanation as to what it is for or whom. Quatermass joins Broadhead on an official tour of the complex, which he is told has been built to manufacture artificial food. Slipping away from the visiting party, Broadhead attempts to get inside one of the large domes dominating the skyline. Quatermass later finds him dying, covered in a poisonous black slime.
