André Semeur recounts how his wife Albane falls gravely ill and is sent to Nice, while he returns to Paris, troubled by her absence; during a business trip to Berlin he meets Professor Krantz, a distracted but respected scientist, who tells him he is working not to cure disease but to overcome death itself, asks for secrecy, and suggests success may be near; later, Semeur returns to Berlin and visits the modern institution at Grunewald, where he encounters Krantz again, who claims his discovery has been achieved and that he himself is dead yet kept in motion by a mechanical device replacing his heart, producing a regular ticking, though this is later contradicted when Dr. Lautensack explains that Krantz is in fact a patient suffering from delusion, believing a watch against his chest sustains his life, and Krantz subsequently dies when the watch stops.
