 Dr. Lee and his team have modified one of the virtual reality chairs last seen in "The Gamekeeper" to host a combat simulation for training Stargate personnel. After claiming the simulation isn t realistic, Teal c agrees to help the scientists refine it. Inside, he faces steadily mounting hazards. Worse, his own ego prevents him from leaving until the last Goa uld is destroyed. Each time he dies in the scenario, the chair shocks him. Teal c must find a way past the barriers of his own mind to escape before the virtual deaths sum to real fatality.
