Perpetrators of violent crimes have often been called monsters, but on NBC's new crime procedural Grimm, which premieres Friday, Oct. 28 at 9/8c, the criminals are monsters — both literally and literarily.

It turns out that Grimm's Fairy Tales isn't a work of fiction, but an account of supernatural creatures that the Grimm family has destroyed throughout history to keep humanity safe. Portland cop Nick Burckhardt (David Giuntoli) has just discovered he's the last of that line of hunters, who have a gift of spotting the true, monstrous nature underneath the creature's magically mundane facade.
