NBC’s Grimm

"Grimm" is a drama series inspired by the classic Grimm Brothers' Fairy Tales. After Portland Homicide Detective Nick Burkhardt discovers he's descended from an elite line of criminal profilers known as "Grimms," he increasingly finds his responsibilities as a detective at odds with his new responsibilities as a "Grimm.”

His attempts to shield his fiancée, Juliette Silverton and his partner, Hank Griffin, from the hazards of his new life have reached a crisis, leaving Juliette in a mysterious coma and Hank on the verge of a mental breakdown.

With help from his confidants, Monroe and Rosalee - both reformed Grimm creatures (Wesen), Nick must help those closest to him while still facing off against all manner of ancient evils, including royal lines dating back to the original profilers themselves, the Grimm Brothers. As Nick develops his ability to harness his inner Grimm, he begins to question what he once knew, never more so than when he is reunited with his mother, also a Grimm, whom he thought dead for the past 20 years.

Wesen
