Gonococci have entered the body through sexual intercourse. The White Blood Cells are forced to fight an uphill battle with the gonococci, who are known for their unbelievable proliferation rate. The gonococci have invaded the areas surrounding the urethra and are closing in on the epididymis where the sperm are. In order to stop any further advancement of the gonococci, White Blood Cells wage an all-out war against them in the lymph node. Meanwhile, Red Blood Cells have been assigned with the dangerous task of delivering oxygen to the urethra.
Alcohol, smoking, and stress—in the body subjected to these irritants, the cells responsible for maintaining life seem to fight a war that never ends. Due to a severe shortage of workers, Red Blood Cell AA2153 has to quickly learn to deliver oxygen and collect carbon dioxide, even in dangerous conditions. Meanwhile, White Blood Cell U-1196 has to do her part by dealing with germs and viruses during life-threatening situations. In the midst of these crises, they have to work together to keep the body healthy, despite not knowing if their sacrifices will be worthwhile. Cells at Work! Code Black takes a different approach by showing the grittier side of the jobs our cells perform.
