In this chapter, the miniaturized submarine Proteus becomes trapped in an arterio-venous fistula within the patient's circulatory system, unable to advance or retreat. The mission leaders debate the risks of stopping the patient's heart temporarily to allow the Proteus to pass safely through the heart chambers, a maneuver fraught with danger but seen as the only viable option. The crew inside the Proteus prepares for the perilous journey through the heart, while the external medical team coordinates the heart stoppage and revival.

In this chapter, the crew aboard the Proteus navigates the pleural lining of the lungs, facing technical and medical challenges including a critical failure of their laser equipment essential for the operation. The team debates the risks and alternatives, with Grant taking decisive action to cannibalize parts from their wireless system to repair the laser, prioritizing the patient's survival over communication. The chapter explores the physical environment inside the human body and the psychological states of the crew as they confront the mission's dangers.
