But then cyanide is discovered and one of the patients takes it from the assistant Dvoracek, who borrowed it for an unauthorized experiment. Trojan pairs the cyanide with a gunshot and slowly begins to suspect that someone is trying to kill him. At first he suspects Dvorak, who might become the foreman after his death, but later, as he falls deeper and deeper into a psychosis of fear and apprehension, he begins to suspect everyone around him...
