Hick State County, in the USA's Deep South, is home to the infamous Big Mutha Truckers Haulage Company. That's about to change though, as proprietor Ma Jackson has announced she's planning on retiring. Her dilemma is who to leave the company to... Ma has four very different kids and choosing a successor should be done fair and square. The solution is simple: Ma's going to hold a "trial by trucking!" The one who can make the most money buying, selling and hauling cargo around the County in sixty days will inherit the company when Ma retires. Can you truck 'n' trade your way to the top? There may be some sibling rivalry along the way (not to mention obstacles of other types...), but as Ma always says, "When it comes to business, family don't mean squat!"
