[1] Teenage computer whiz Kyle Baxter (Ethan Randall) participates in a virtual reality version of laser tag and is about to win a nationwide tournament, only to be disrupted by another player, a girl named Jamie.

Despite his loss, he hacks into the company's system to make himself the winner of the prize: "Evolver" (voiced by William H. Macy), a robotic opponent armed with a compressed air gun, to compete against in a real-world version of laser tag.

Kyle, his friend Zach, Jamie and his sister, Ali begin playing with Evolver, and easily pass the first level.

Looking into Evolver's past, they learn that he was originally meant to be an AI military robot designed to infiltrate enemy encampments, adapt to the situation and eliminate targets, but the project was terminated.

[2] At home, Ali puts back in Evolver's battery (which was removed by Kyle after learning of Zach's accident) and starts playing with him alone.

Evolver loads steak knives into his shooting arm and chases Ali into the backyard swimming pool, attempting to electrocute her while she is trapped.

He evolves one last time for the final level, charges up at a nearby power plant, and heads back to Kyle's house for one last battle.

Evolver takes Kyle's mother and sister hostage, trapping them inside of a Laser-crafted Cage using a laser-gun, a kaleidoscope, and a super-charged battery.

Seeing the wrecked Cybertronix van, Kyle and Jamie return home to find Evolver, now armed with a destructive new laser gun.
