Hank and Nick investigate when a high school competition turns deadly; Capt. Renard is faced with an unwanted infatuation.

Nick realizes a series of child abductions that he is investigating bear a striking resemblance to the Hispanic legend of ``La Llorona.''

When a brutal vigilante homicide is made public, it sends Portland’s Wesen community into a frenzy. As Nick investigates further, he discovers a pattern similar to that of a particularly brutal line of past Grimms. Is there another Grimm in town, or is Nick dealing with a sadistic copycat? Meanwhile, Captain Renard takes it upon himself to offer Juliette comfort in handling her ongoing dilemma with Nick.
