Nick Burkhardt (played by David Giuntoli) is a homicide detective for the Portland Police Department. You would think that a heavy job like that would be enough to keep anyone busy but he finds out that he is a Grimm and that really keeps him hopping. A Grimm is a human who can see Wesen (all different kinds of supernatural creatures) and is tasked with killing them before they harm humans. His plate is full because Portland seems to be a hotbed of Wesen activity and criminality. At first he keeps his ability and the existence of Wesen secret from his partner Hank (played by Russell Hornsby) and girlfriend Juliette (played by Bitsie Tulloch) but that becomes too much and he has to divulge everything to them. On top of all this in season three Nick has to deal with the fact that his captain, Captain Renard (played by Sasha Roiz), is also Wesen and a member of a royal family in Europe and that one of his best friends, Monroe (played by Silas Weir Mitchell), is a Wesen who is marrying another Wesen named Rosalee (played by Bree Turner). A series that is from the minds of the producers from Buffy: The Vampire Slayer and Angel.
