In a remote space station on Titan's moon Saturn 3, scientists Adam and Alex lead a tranquil yet isolated existence, conducting research to support an overpopulated Earth. Their solitude is disrupted when Benson, a mentally unstable Earth pilot, arrives with a new high-tech robot named Hector. Initially introduced as an advanced assistant to help with their work, Hector soon becomes a source of tension as Benson’s neurotic behavior and obsessive tendencies begin to influence the robot's programming.

As Hector grows more erratic and dangerous, Adam and Alex find themselves in a perilous situation, struggling not only to continue their vital research but also to survive the escalating threats from both Benson and his increasingly uncontrollable creation. The tight-knit environment of the space station becomes a battleground for control and survival, where the once peaceful atmosphere transforms into one of suspense and danger.
