Jayce's Dad is a plant scientist who creates the Brain which is the hybrid plant human that can talk telepathically. Jayce is trying to find his father and get the help of a bootlegger who ends up helping a lot in a moany way. During an experiment done by his father, radiation infuses the plants with evil, and create the Monster Minds, sentient plants that can transform into vehicles. Vehicles can also be spawned from mutated vines. The only way to defeat the Monster Minds is to expose them to the Magic Root, of which Jayce and his father each have a part. In order to find his dad, Jayce uses some of his father's last creations, including five vehicles created for the Lightning Leage. These can operate independantly through an A.I. system, or be driven.
