Four very unequal children at the age of 6 until 11 are chosen to become the new soap box racing team to compete at the secret "Castle", where all the world champions of racing have participated, when they were kids. A selective group of boys and one girl have nothing in common but their passion for cars and racing. Their first big challenge is to unite as a team by becoming friends, only then they will have a chance of winning.
