Responding to a distress signal from a sector of space where ships disappear every 27.346 years, the male crewman are affected by a signal. Uhura and Chapel are forced to take command when the male crew onboard starting acting enraptured. On the plan... (more)et's surface, Kirk, Spock, McCoy, and a redshirt are first greeted than captured by the women and given headsets that suck out their energies and cause their bodies to deteriorate as if they were aging. They escape but in their enfeebled condition are trapped in a giant urn filling with rainwater. Uhura leads a landing party that defeat the women readily and find the men. The women's physiology and life-energy requirements are keyed to the planet, and Enterprise agrees to take them to a normal planet. Using the transporter and the original patterns, they restore Kirk and the others.
