Quatermass(1979)

Quatermass is a science fiction series following the aging Professor Bernard Quatermass as he uncovers a chilling mystery surrounding his granddaughter's disappearance. When she vanishes without trace, Quatermass discovers her connection to a sinister cult operating in the shadows of near-future Britain. His investigation pulls him into a web of conspiracy and otherworldly terror that challenges everything he thought he knew. Blending hard sci-fi concepts with genuine dread, the series sees the legendary scientist—now past his prime but still sharp—race against time to rescue his family and expose a threat far larger than anyone imagined.
