A thousand years from now, Earth is a disaster. The surface is nearly unlivable outside of domed cities, with the more well-off living in stations and colonies in space. The task of reclaiming Earth is long and hard, even with the available technology. But now an alien armada has arrived to test human society in a game that will decide whether they join interstellar society or are destroyed for the good of the galaxy.

The problem is that no one on Earth has played any sports games in centuries. Fortunately, there is an experimental time travel machine that may allow them to bring forth some sports figures from Earth's past to play the alien game, a game with a few similarities to basketball. A fault in the machine, however, only allows one notable sports figure and his companions to be brought forth, snatched moments before their reported deaths in a helicopter crash.

Now it's up to Kobe Bryant to play the game of his life and save the world and all of humankind.
