Payton ( Dennis Quaid ) and Bower ( Ben Foster ) are two astronauts who are on duty on a spaceship. At least that’s what they both know. The two of them woke up from a hibernate condition and realized that they both couldn’t remember anything that had happened before.
In their confusion, they concluded that only the two of them were left on the abandoned plane. Not knowing the direction their plane was headed and where they came from, Payton and Bower then tried to investigate what had actually happened to the other aircraft and crew. The only way to investigate is by tracing the aisles of the airways that connect their space with other rooms.
Bower then began to trace this airway with the help of Payton who was watching from behind. The only communication tool they could use was the communication radio left there. The farther Bower was, the more the mystery of the loss of their memories and what had actually happened to their plane was revealed.
