Selena Castillo publicly claims to be an extraterrestrial. Is it a joke, a delusion, a gimmick, or a reality? Tony Sturgess must believe that Selena's claim is only a publicity stunt, or that she is insane, as he falls in love with her, because he still struggles with the racism of his white-supremacist childhood; otherwise, he is certainly the right talent agent to exploit the gimmick, despite her radical environmentalism. Professor Hal Bronson, on the other hand, is desperate to believe Selena's claim after he is labeled a "crackpot" for hypothesizing that the SETI silence is due to a global technological catastrophe that every advancing civilization must face: she might be a witness. But if Earth is to be saved, from whom and for whom will it be? Through humor, romance, and suspense, MINE entertains while its human characters resolve a case of mistaken insanity.
