Our CSIs investigate the murder of two men who were about to expose a natural gas conglomerate of poisoning residents in a farming town. When a Natural gas company leases land to poor ranching families outside of Vegas, the water starts to poison the population. people start getting terrible cancers, and dying off. The two men who try to investigate the company are both murder in a pay off by the big corporation. Langston and Nick attempt to solve these murders, and at the same time encourage Ecklie to go after the corporation. Ecklie will not have it -- not their jurisdiction. In the end they solve the murders, and find out that that man who was paid off by the big gas company was also murdered.
