David Giuntoli

In the world of Grimm, everyday crimes like breaking and entering can unlock some surprising dangers.

On Friday's episode (9/8c, NBC) Nick and Hank (David Giuntoli and Russell Hornsby) investigate a home-invasion case and run across a family with a cultural background including a barbaric history perhaps best left in the past.

Ratings: Grimm's debut is anything but

Check out this first look:

Hmmm. The episode is titled "Bears Will Be Bears" and features a blonde named Gilda (Amy Gumenick) who's just been in a house that's obviously not hers. It sure sounds like "Goldilocks and the Three Bears," but since this is Grimm, we're expecting a few twists. Porridge may not be involved!

Grimm airs Fridays at 9/8c on NBC.
