Season one of new supernatural crime drama Grimm gets its UK premiere tonight on Watch at 9pm.

Made by the brains behind Buffy The Vampire Slayer and Angel, come a brilliant world of police work where all cases have a storybook connection… but not always a happy ever after. Grimm puts a dark new twist on the Brothers Grimm stories where the fairytales adored by generation are real, and only one person can stop the villains.

In the pilot episode:

After the mysterious brutal attack of a local college co-ed, Portland homicide Detective Nick Burkhardt discovered he is descendant of an elite line of criminal profilers known as “Grimms,” charged with keeping balance between humanity and the mythological creatures of the world. As he tries to hide the dangers of his new found calling from his fiancé, Juliette Silverton, and his partner, Hank Griffin, he becomes ever more entrenched in the ancient rivalries and alliances of the Grimm world. With help from his reluctant confidant, Monroe, a reformed Grimm creature himself, Nick must navigate through the forces of a larger-than-life mythology.
