After crash landing on an alien world, John Virgil conducts an exterior examination of the spacecraft. He is bitten by a spider-like creature but manages to get back into the airlock. He awakens to find himself in a hospital with his wife and son anxiously by his bedside. It's all an hallucination however when he realizes he's still on board the ship. His colleague Dr. Vasquez tells him the hallucinations are the result of the spider venom but as he flashes back and forth between the hospital and the spaceship, he can't distinguish which is real.
