In  the future a strange epidemic conquers an Earth already overrun by pollution and revolt. Those who succumb fall into their dreams, vanishing on strains of music into a perfect void that enthralls like a paradise and binds like a prison.  The Stalker is one of those few who are immune and who are able to travel through the dream world of the virus to rescue others. As he carries out rescue after rescue, he becomes more and more embroiled in  the politics surrounding the virus and its cure.
