Laura enters her office one night to find three teenagers ransacking her files for information on telepathy. Seeing Laura, the teens mentally “join forces” and traumatically erase Laura’s memory of them. J.J. uses hypnosis to restore Laura’s memory; they investigate and find that the teens have combined their individual telepathic talents to form a “group mind”. One teen, Jamie, becomes frightened by the Mind’s misuse of its power and comes to Laura and J.J. for help getting out. Laura and J.J. must then defend Jamie against the mental assaults of the Mind as it attempts to force Jamie back into the fold.
