Synopsis by Hal Erickson
The Unearthly Stranger takes a romantic approach to standard sci-fi material. John Neville marries mysterious Gabriella Lucidi, but begins questioning his judgment when his new bride exhibits some curious behavioral traits. When he discovers that Lucidi has no pulse, Neville is really thrown for a loop. Inevitably, Lucidi reveals that she is a visitor from another planet, sent as the vanguard for an invading alien army. Neville could live with this, save for the fact that Lucidi's mind is being controlled by her outer-space superiors, forcing her to induce the deaths of anyone who draws close to her. Ultimately, Lucidi sacrifices herself for Neville, with whom she has truly fallen in love.
