"Man's closest encounter"

"A million lightyears from home, she's found a husband, a stepdaughter and a dog. When she finds out about sex, she may just stay for weekend."

Plot:

Celeste (Kim Basinger) is an alien sent on a secret mission to Earth; Steven Mills (Dan Aykroyd) is a widowed scientist who is working on experimental ways to send radio waves into deep space. An accident causes a loss of gravity on Celeste's home world. She's sent to investigate who could affect gravity and how it was done under the belief it was an attack. She's 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 misbelief that it was current (her superiors had just collected the information, which had taken 20 light years to get from Earth to her homeworld).


Celeste's inexperience leads to her almost exposing herself as alien, 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 cigarette butts and flashlight batteries or pulling hard boiled eggs out of boiling hot water with her bare hands. However, she can't convince her smitten father that there is something 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.


Celeste encounters a lot of new experiences such as sneezing, sexual intercourse and love. When Jessie finally confronts Celeste about being an extraterrestrial, Celeste admits her homeworld is without emotion, and will depart once she discovers the truth, but is put in a quandary by Jessie, who says it will devastate her father. After Jessie argues with her dad she runs away and is nearly hit by a car, but is saved by Celeste's powers. This reveals to Steven Celeste is indeed an alien, and that she has fallen in love with him as well as accepting Jessie as her own daughter. When the leaders of Celeste's homeworld report in, she and Steven try and convince them it was not an act of aggression, but a scientific mistake. They accept the explanation on the basis that gravity is returning to their planet and give their blessing for Celeste to be with Steven, but ask for a native of Earth to serve as ambassador to their world as a token of goodwill. The ambassadorship is accepted by Ron, who departs for Celeste's world in a spaceship served by several flight attendants, all of whom look like Princess Stephanie.
