Colonists from a dying Earth, barely escape a rebel plot to seize their ship, the ARROW, and blast off from Luna Base for Alpha Centauri. As they lay sleeping in their suspended animation pods, a collision disables the ship and sends it careening far off course. When they awake 128 years later, they find themselves orbiting Vlor, a planet ravaged by ancient wars, where men are kept as slaves for heavy work and for breeding purposes. Punishment bands locked on their bodies keep the men helpless, unable to resist. With his ship useless, Captain MacKenzie and his crew have no choice but to submit to the women of Vlor. MacKenzie accepts slavery for himself and the male members of the crew in exchange for citizenship for the female crew members. The men are enslaved on farms where they labor in the fields and then have their semen "extracted" by a mechanical device in the most humiliating manner imaginable. On a world where the population is declining, the sperm harvested from the men of the ARROW is precious, and in time MacKenzie is able to wrest concessions from the Vlorians. There is plenty of intrigue as one faction of the ruling council kidnaps MacKenzie and keeps him prisoner at a secret location. There is also an exploratory tour of other parts of the devastated, feudal planet and love for MacKenzie with the beautiful Forlana before MacKenzie finally discovers peace and contentment on this alien world.
