The Invaders

Architect David Vincent witnesses a flying saucer land and its alien occupants emerge. He tries to convince a disbelieving world that aliens are secretly infiltrating Earth, posing as humans and systematically taking over. Each episode features Vincent encountering new invaders and attempting to thwart their plans, often with the help of people who gradually come to believe him, though they are frequently too late.

While some critics at the time noted its sometimes repetitive formula and the inherent difficulty of proving the existence of unseen alien invaders, it has since become a cult classic, praised for its paranoia-fueled narrative that resonated with the anxieties of the Cold War era.
