Alec Byrne is the only survivor to the crash of his vessel on the turbulent Considjar, dominated by four alien races fighting against each other for the dominance of the planet. After years of vicissitudes and dangers, Alec and four companions embark on a difficult journey aboard a stolen spaceship, towards the coveted Planet Earth.

For Alec Byrne it is the return home but for his companions, natives of Considjar, where humanity is confined to the last place of the social hierarchy, the journey - a leap in the dark - represents the possibility of redemption from a life of misery, violence and abuse: the last chance for an existence at last as free men.
