If there’s one thing I learned after watching the pilot episode of “Grimm,” it’s to leave my red hoodie at home the next time I head out for a jog.

In the opening scene of this new crime drama, premiering Friday, Oct. 28 at 8 pm on CTV, a university student heads out for a run (dressed in a red sweatshirt, of course!) and is savagely attacked by a creature that the homicide detectives can’t identify.

All of a sudden, Little Red Riding Hood’s tale doesn’t seem so happily ever after.

Watch a 20-minute sneak peek now.

“‘Grimm’ is unique in the world of cop shows in that it is a procedural cop drama, but instead of mafia criminals and drug dealers, we have creatures from fairy tales doing very dark things in a very real world,” says actor David Giuntoli, who plays Detective Nick Burkhardt, in a pre-taped press interview.

And he’s not kidding. There are no singing mice and dancing teapots in this fairy tale world, instead, strangers morph into horrible creatures and even the prettiest girls turn into snarling ghouls. But for some reason unbeknownst to him and to us, Nick is the only one who can see their true selves.

“Nick is a very fun character to play in that he had this perfect life, he was very much in control, on the straight and narrow, with a wonderful fiancée…and wonderful job and my whole world is upended 15 minutes (into) our pilot episode,” says Giuntoli.

Upended might even be an understatement.

When out for a walk one night he and his aunt (Kate Burton) are attacked by one of these unworldly creatures and Nick ends up killing him.

It is only then that ailing Aunt Marie reveals she and Nick are descendants of an elite group of hunters, also known as "Grimms," who fight to keep the balance of humanity safe from the supernatural creatures of the world.

This explains all of the freaky people Nick keeps seeing.

But it’s not entirely black and white with the evil fairy tale creatures squaring off against the police force.

Eddy Munroe (Silas Weir Mitchell) plays a Blutbad, the German version of the “Big Bad Wolf,” except, he’s a “reformed” werewolf.

“As you can see, I’m not that big and I am done with the bad thing,” he tells Nick, crediting “a strict regimen of diet, drugs and Pilates.”

In fact, he and Nick sit down and have a beer together, and Eddy even helps Nick find an evil Blutbad who kidnapped a little girl who was on her way to her grandfather’s house in a red hoodie.

“You have compassion for someone who is an evil creature on a certain level, but these impulses are universal, the impulse to love and the impulse of death,” Mitchell said in press materials for the show.

“It’s not just about crime, not just about forensics or the law, it’s about these things and a deeper level of human experience.”
