Miki Rosa, a professor of mathematical theory, took a fancy to him and thought he was a plastic genius, and his future would certainly not be bad. After a short contact, Teacher Rosa introduced Ben Campbell to several other students, and invited Ben to join a "special group", which is composed of people who are very talented in the field of mathematics, such as Jill and Fisher, who specialize in the casino "2 1" game and make use of their mathematical knowledge.
After a period of training and careful preparation, Professor Rosa and several students came to the casino to play "2 1", hoping to win more than three million dollars, but they have been targeted by professional investigator cole williams, and they have no clue.
