Taglines: She's gorgeous, and she's never been kissed. Needless to say, she's from another planet. My Stepmother Is an Alien movie synopsis. Celeste (Kim Basinger) is an alien sent on a secret mission to Earth and Steven Mills (Dan Aykroyd) is a widowed scientist who is working on different ways to send radio waves into deep space. An accident causes a disruption of gravity on Celeste's home world (Cosine N to the 8th). She is sent to investigate who could affect gravity and how it was done, believing it was an attack. She is aided by an alien device resembling a tentacle with an eye, which hides in a designer purse to aid Celeste with her encounters on Earth. The bag is able to create any object, such as diamonds and designer dresses almost instantaneously. Celeste crashes a party hosted by Steven's brother Ron (Jon Lovitz), where she immediately draws attention to herself by making dated references to old TV shows and political slogans under the mistaken belief that it was current (her superiors had just collected the information, which had taken 92 years to get from Earth to her home world). Celeste's inexperience almost results in her exposing herself as alien when she struggles with simple tasks like trying to kiss for the first time or cooking. Jessie Mills (Alyson Hannigan), Steven's 13-year-old daughter, notices Celeste's strange habits, like eating car batteries and pulling hard boiled eggs out of boiling hot water with her bare hands, and becomes suspicious of her. However, she cannot convince her smitten father that something is unusual about Celeste. Ron also has his doubts about Celeste, but more on the basis that he feels his brother is doing too much too soon by asking to marry Celeste only a few days after they first met. Ron tries to dissuade Steven from marrying Celeste on the idea she is an illegal immigrant or planning economic espionage, but then admits he is jealous his brother found his dream girl whereas he will never find a girl like Princess Stéphanie of Monaco.
