My Stepmother Is an Alien is a science fiction comedy film directed by Richard Benjamin and released in 1988. The movie stars Dan Aykroyd as Steven Mills, a scientist who falls in love with an alien named Celeste, played by Kim Basinger. Jon Lovitz also appears as a sleazy tabloid reporter named Ron Mills, who just so happens to be Steven's brother.

The story of My Stepmother Is an Alien revolves around Celeste, an alien from the planet Cosine N to whom Earth is just one of many planets in the universe. She is sent to Earth by her leaders to investigate the possibility of intergalactic travel and to learn more about humans. While on Earth, Celeste meets Steven, a scientist who is working on a project that involves sending a laser beam into outer space. Steven is immediately drawn to Celeste's unique personality and beauty, and the two quickly fall in love.

However, Steven soon realizes that there is something strange about Celeste. She has a robotic voice and is not familiar with common Earth terms or customs. It is then revealed that Celeste is actually an alien who has been sent to Earth to complete a mission. Despite this revelation, Steven continues to pursue a relationship with Celeste, taking her on dates and showing her the wonders of the planet. Meanwhile, Ron, Steven's sleazy brother, is determined to expose Celeste's true identity to the world.

As the movie progresses, Celeste and Steven's relationship becomes more complicated. Celeste's superiors on her home planet Cosine N have discovered that she has fallen in love with an Earthling and that her mission to study humans has been compromised. They give her a deadline to complete her mission or else they will recall her back to Cosine N. This puts pressure on Celeste to focus on her mission instead of her relationship with Steven. Additionally, Ron's attempts to expose Celeste's true identity creates further problems for the couple.

Ultimately, Celeste must make a decision about whether to stay on Earth with Steven or return to her home planet. She realizes that being on Earth has changed her and given her new perspective on life. However, she also knows that she has responsibilities to her home planet and must fulfill her duties as a scientist. The movie ends with Celeste making a choice about her future and Steven realizing that he may have to continue his life on Earth without her.
