The Gamekeeper

The Gamekeeper is the fourth episode of the second season of Stargate SG-1.

Plot
SG-1 visits a world and finds itself in a large beautiful garden, but then they find out that all people on the world are tied to some machines. Suddenly all team members are captured by some empty machines. Afterwards they are separated and find themselves in other places.

Col. O'Neill and Teal'c find themselves in a wooded area and suddenly meet other human soldiers from Earth, including Charles Kawalsky, who died one year ago. O'Neill then recognizes this place and remembers that this was the time of an undercover mission in East Germany, where one of them died. However the soldiers act as if Teal'c is one of them and call him "Thomas". Because they think that they might have travelled through time, they again go through the mission. However it again goes wrong and suddenly the mission starts again from the beginning. This scenario happens over and over again and O'Neill isn't able to change the outcome.

Daniel Jackson and Captain Carter in the meantime find themselves in a museum and Jackson remembers it as the time when his parents were killed by falling stones. He also tries to change this event several times but also fails.

Back at O'Neill and Teal'c they are visited by a strange man named the "Keeper", who tells them that he offers them the possibility to change the past - albeit only in a simulation. Afterwards he also visits Daniel and Carter and tells them the same. However all members of SG-1 decide that they won't take part in this simulations anymore and refuse to do anything. Because of this the Keeper brings all the team members back together and tells them that over 1000 years ago a chemical disaster took place which destroyed this world. Because of this the whole civilizations entered stasis and now they want more scenarios for their virtual world. Because Teal'c's and Carter's brain can't be accessed (Jaffa are apparently immune to the process and Sam's mind has been altered by Jolinar), the Keeper lets them take part in the simulations of their friends.

While they talk they are watched by many people (the other inhabitants of the virtual world) and when they hear that the outside world has recovered, they react. However the Keeper then sends them away and finally lets SG-1 free. The team then returns to Earth, where they are checked in the infirmary and then report to General Hammond. However the General tells them to get more information about this virtual world, which would mean that they would have to be hooked up to the machines again and Hammond orders them to do so. Due to his uncharacteristic behaviour, SG-1 then concludes that they are still in the VR and O'Neill attacks the General, who then orders them to be arrested.

In the cell they are visited by Kawalsky who tells them that they simply should stay in the VR. However the team then escapes and suddenly meets the residents of the VR, who ask the team about the outside world. They tell them that outside a beautiful garden exists. Afterwards they chase the Keeper, who was disguised as Hammond and suddenly they are freed- this time for real. They then capture the Keeper in the garden and demand to know why he didn't let out the people. He tells them that they would ruin the garden which he manages and finally the whole world, thus repeating their former mistakes. However they suddenly see that the people have already left the VR and now go through the garden and pick flowers, much to the anger of the Keeper. Promising to return and help the residents begin new lives, SG-1 returns to Earth.
