For the Universal Alliance, someone else's life is just a resource that can be used. They live on huge space stations roaming space. Their maintenance constantly requires energy. They turned the planets into their batteries, and the inhabitants of the Universe into unquestioningly obedient subjects. Their power is limitless. But one day they learn that in one of the galaxies a valuable energy planet was deliberately destroyed. And it was destroyed by a representative of the human race named Rendal. They send the Quadeterian detective Yundel, a former "bounty hunter", after him.
