It was a hot day, the body suffers from heat stroke, leading to a heat wave inside and the supply of fluids being depleted. To make matters worse, a Bacillus Cereus, who is not bothered by the heat, invades the body. While the other cells struggle to cope with the extreme heat, U-1146 pursues the bacterium, but grows fatigued. Just when it seems that all is lost, the body gets an injection of fluids, reviving everyone and allowing U-1146 to kill the bacterium.
