1999 yapımı The Thirteenth Floor (13. Kat) filminin İngilizce anlatımı şu şekilde özetlenebilir:

The story is about the story of people who create a life simulation with advanced computer technology 5. They have produced software robots in the form of humans who live in a life designed in the 1930s by interacting with each other 5. They can also include themselves in this simulation 5. They do this by transferring their own consciousness into the consciousness of one of the characters they have created 5. Thus, they move to a different plane of existence from their own plane of existence 5.

What they see surprises them, because they witness that the "people" in the "lower" plane of existence have developed consciousness just like themselves 5. But this witness produces a terrifying question: what if they are also a simulation created by "creators" at a higher level of consciousness 5?

The film tells the philosophical questions such as "who are we?", "what is the meaning of our existence?", "what is consciousness?", "can there be different levels of reality from the one we are living in?" 5.

The film opens with René Descartes' famous "cogito, ergo sum" (I think, therefore I am) 5.

The plot has certain parallels with existential themes handled in Welt am Draht, The Matrix, and Open Your Eyes 4.

The film was nominated for the Saturn Award for Best Science Fiction Film, but the award went to The Matrix 4.
