In this supernatural series there is no knight in shining armour coming to save the day. Instead, our unlikely hero is homicide detective, Nick Burkhardt (David Giuntoli).
When Nick begins to see things that he can't quite explain ? beautiful women transforming into hideous hags and average Joe's evolving into vicious trolls ? he begins to question his sanity. A panicked visit from his aunt, Nick's only living relative, reveals everything.
He is the last remaining descendent of a group of hunters known only as ?Grimms?, who are charged with the task of keeping the world safe from sinister storybook creatures.
Grimms are destined to take on the frightening fairytale characters believed to have been invented by the Brothers Grimm. Now, while fighting crime on the streets of Portland, Nick must work to keep the balance between myth and reality.
In Grimm, there are no such thing as bedtime stories. Everywhere Burckhardt looks he sees monsters. Destined to take on the misfortune of his family, Nick becomes ever more entwined in the ancient tales. He finds it hard to hide the dangers of his identity from his fiancé, Juliette (Bitsie Tulloch) and his partner, Hank (Russell Hornsby).
The only person Nick can trust with the truth is Monroe (Silas Weir Mitchell), a reluctant informant and reformed Grimm creature, who helps him unravel each case. Nick must navigate through the forces of a larger-than-life mythology, facing off with Hexenbiests, Blutbads and all manner of ancient evils, including royal lines dating back to the original profilers themselves, the Brothers Grimm.
