Elias Hund is back, and he looks to his twin brother, Franz, on this extraordinary journey to save nature's overlooked and threatened flying mammals. With very little to go on, they would once again need to infiltrate a well-funded and heavily armed poaching ring. A seriously demented and determined mind protected the ring of wildlife violators. One that believed the key to artistic beauty hides behind the eyes of the dead. Meanwhile, Franz is caught in a sense of Déjà vu, reflecting upon a similar situation that occurred 15 years prior. Occupying his thoughts and hurting his performance, the previous experience has his soul bracing for impact. Have the Hunds met their match?
