When animal behaviorist Guy Schermerhorn demonstrates on a TV game show that he has taught Sam, his juvenile chimp, to speak in sign language, Aimee Villard, an undergraduate at Guy's university, is so taken with the performance that she applies to become his assistant.  A romantic and intellectual attachment soon morphs into an interspecies love triangle that pushes hard at the boundaries of consciousness and the question of what we know and how we know it.  

What if it were possible to speak to the members of another species—to converse with them, not just give commands or coach them but to really have an exchange of ideas and a meeting of minds? Did apes have God?  Did they have souls?  Did they know about death and redemption?  About prayer?  The economy, rockets, space?  Did they miss the jungle?  Did they even know what the jungle was?  Did they dream?  Make wishes?  Hope for the future?
