The unwilling police inspector Klaus Pistor is sure that Talan is the murderer but has to let Kate and her team work. There is turmoil in the precinct and Gavin is scratched by Talan. Then they visit Talan's mother Mrs. Gwynek and they learn that Talan has a rare disease. Further, the government wants her lands to dispose nuclear waste and her husband has recently died in car accident. Soon Eric discloses that the death of Mr. Gwynek was suspicious and Pistor was in charge of the investigation. When Kate succeeds in sending Talan to a hospital for examination, she discovers the effects of Talan's disease and is the responsible for the next events. 看来我需要写一篇科普贴。 一家人在森林裡露營，突然遭逢意想不到的災難，僅有媽媽勉強逃出。驚魂未定的她向警方求助，表示她的丈夫和兒子被一位男人活活生吃。警方半信半疑，但隨即逮捕了住在那片森林裡的一位神祕男子——泰倫。 律師凱特被指派為泰倫辯護，為了釐清狀況，她帶著動物學家要求對泰倫進行身體檢查。即便警方認定泰倫就是兇手，他們還是同意讓凱特進行調查。然而，在檢查時，泰倫卻做出了可怖的舉動…。凱特不得不找上泰倫的母親，出乎意料的是，他的母親表示泰倫身上有某種疾病…。泰倫究竟是患病的人類還是某種非人物種，而凱特會採取什麼樣的行動為他辯護呢？
