Evolver

“It was supposed to be a game.”

In 1995, a laser tag arena is the center of Kyle Baxter's world, and he's good enough at it to win a contest there. His prize is Evolver, a robotic opponent voiced by William H. Macy, which Kyle (Ethan Embry) brings home to play against. Mark Rosman sets the game loose in a family's house, and what's at risk is no longer a score.
