Mad-Cap research scientist and adventurer, Jeffrey Shenero, finds himself caught up in a terrible plague sweeping across a large portion of the nation, as countless evaporative coolers begin exuding a green slime that smells like dead fish. A dark cloud of disease-causing insects in astronomical numbers surrounds every affected home, driving the residents to the streets, filling the hospitals with patients. Tent cities crop up everywhere. His pending fatherhood leaves Shenero reluctant to become engaged in solving the problem, while his alluring doctor wife, Carmen, tries to counsel him. Assisted by their Swedish researcher, Ingrid, the three find themselves in constant disbelief as new developments occur almost daily. When Jeff does become involved, challenging side investigations interfere with everyone's time table, adding frustration to the seething cauldron, which ends in a damning critique of bottled water. Mike Sutton, a tortured war hero with PTSD, who services the coolers involved in the epidemic, tries to assist them, yet he is thought to be behind a possible plot to kill Americans. Unbeknownst to anyone, the suspected plot turns real and much deeper than any of them thought. International forces are at play to bring down the United States in a bizarre manner, while Jeff and his crew chase false leads, forcing Jeff to play hard ball, with the assistance of the Department of Homeland Security.
