The Ultimate Vampire Resource and Directory

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 during one of his experiments inadvertently caused gravity to be ruined on Celeste's home world. Celeste is then sent to Earth to find out who has discovered a way to change gravity and how they did it. She is aided by an alien or alien device, resembling a large phallus with an eye, who hides herself in a designer purse to aid Celeste by indoctrinating her on Earth ways. The Bag is able to do amazing things like create diamonds and designer dresses almost instantaneously.

Celeste's newness on earth leads to some humorous situations where Celeste nearly exposes herself as alien due to her strange behavior, like trying to kiss someone for the first time or trying to cook. Jessie Mills (Alyson Hannigan) is Steven's daughter, who notices Celeste's strange habits, such as snacking on cigarette butts and flashlight batteries, pulling hard boiled eggs out of boiling water, and handling an extremely hot oven rack without being burned. However, she cannot convince her father that there is something strange about Celeste, since her father is too smitten with Celeste to care.
