Outside the doors of their school after the final bell of the year, four friends gather to plan their summer break. The first choice is the Video Rental Store. Inside, they find a mysterious console called the Gutsy-Bit. With some convincing, the store clerk, initially reluctant, allows them to rent it. Bringing it back to their usual basement hangout spot, they turn it on and are instantly teleported to a mysterious world where the Gutsy-Bit can channel awesome power via Carts. With their newfound power, these four friends become the last hope to thwart a sinister plot threatening two worlds.
