An environment that pleases one individual may be a nightmare to others. Sara Almquist, an FBI scientific consultant, confronts this truth as she investigates the murder of a young man near a historic cave in New Mexico. As Sara reconstructs the victim's final days, she learns the autistic victim found the cave to be soothing. She finds the cave to be depressing. Maybe, Sara dislikes the cave because the case is so complicated. She's also having trouble breaking in a young partner-Jack Drum. Or perhaps, she's distracted. Sara and her long-term boyfriend-Eric Sanders-have come to recognize the disparity in their goals and comfort spots.
