Sergeant Wu's in for his own rude awakening as Nick and Hank introduce him to the world of Wesen and admit that they had been lying to him for a long while. Wu's introduction, however, is interrupted by Rosalee's desperate call for help. Juliette, meanwhile, is unable to tell anyone about her own horrifying experience transforming into a Hexenbiest because of the Monroe kidnap situation.

They question a Klaustreich known to be a member of the Wesenrein, but he feigns ignorance of the whole incident. When he's killed, it seems like their last lead has gone up in smoke. Will they get to Monroe in time? Will Juliette loose control of the violent transformations?
