When you watch Grimm Season 5 Episode 8 online, Nick and Hank are asked to assist in an investigation when an unfortunate tourist is killed while boating on a lake, and his fiancee captured a picture of the legendary "lake monster" just before it dragged him underwater and killed him. Needless to say, they assume that the creature is really Wesen. What they don't know is that the Wesen in question was hired by the local boat rental guys to scare tourists by posing as the lake monster. The guys, two brothers who are also Wesen, attempt to play it cool to hide their involvement in the mess, though what *they* don't know is that one of the detectives investigating the murder is a Grimm. The situation becomes more complicated and urgent when the Wasser Zahne kills a second innocent tourist on the lake. Meanwhile, Martin Meisner invites Nick to take a tour of HW's secret underground headquarters, and gives Nick a chance to talk to Eve once more. Meisner also fills Nick in on the direness of the situation throughout the world in regards to Black Claw. Find out what happens when you watch Grimm Season 5 Episode 8 online!
