A creature from another planet tries to seduce a shy Earth physicist to gain control over his researches. The result of this important mission much exceeded her expectations.

An alien is sent on a secret mission to Earth, where she appears as a gorgeous, attractive, and single lady. Her mission is to make contact with a rather nerdy young scientist, who's quite overwhelmed by her attentions, and isn't aware of the connection between her arrival and his work.—Murray Chapman <[email protected]>

After a widower scientist accidentally sends a death ray to a planet of super advanced aliens, a femme fatal alien secret agent is sent to Earth to reverse the ray within 48 hours, if her super alien powers and complete lack of understanding human culture don't give her away first.—Dollanganger

Widowed astronomer Steven Mills accidentally sends a great surge of energy out into space, threatening life on another world. They respond by dispatching one of their race disguised in deliberately attractive human form (Celeste Martin) to Earth to sort things out, accompanied by a rather less attractive superior (Bag). Steven is indeed attracted, as is his untrustworthy brother, while Celeste becomes increasingly fond of Steven's young daughter.—Jeremy Perkins {J-26}
