Professor Kyle Riggs and his kids were asleep in their house when the alien spaceship arrived. It killed the kids, kidnapped Kyle, and put him through a series of grueling tests. Since he was still alive afterward, the ship made Kyle the captain. This has been happening all over Earth. Most of the captured humans have been killed because they couldn’t make it through the rigorous tests, but all the survivors are now piloting spaceships and in the perfect position to fight off an alien invasion that’s coming to enslave humanity.
