AN ESCAPED FUGITIVE’S MURDEROUS RAMPAGE LANDS AT NICK’S FRONT DOOR — An escapee returns to Portland seeking revenge against those who put him behind bars. His unusual strength and high tolerance for pain makes Nick (David Giuntoli) take notice. As the case escalates Nick and Juliette (Bitsie Tulloch) are put in danger, and Monroe (Silas Weir Mitchell) is called into action to help put an end to the convict’s deadly rampage. Russell Hornsby, Reggie Lee and Sasha Roiz also star.
