Meet homicide detective Nick Burkhardt. He’s not your average homicide detective. Which is handy, because the streets of Portland need a little more than average policing. Following some seriously weird visions, he learns from his aunt that he’s one of the last in a line of guardian hunters called Grimms.

His task is to protect the world from supernatural creatures called Wesen, which are invisible to us regular folks. Murderers are revealed to be ogres or terrifying bat-like monsters, for example. And they’re everywhere. Nick’s girlfriend, understandably, is dubious, until Monroe, his buddy and reformed Wesen, reveals his inner werewolf. She faints, as you would.

The show initially gained a reputation for overly-complicated plots and sub-stories, with weirdly-named monsters and foes popping up left, right and centre. But stick with it. By season 3, it calms down into familiar good-versus-evil action with ballsy characters to gun for.

Fans of Buffy or Angel will love this gang of misfits, fighting supernatural forces and falling in (and out of) love in equal measure. And, when you consider the plot of the average Grimm fairy tale, you won’t be surprised to hear it’s gore galore.

The final series of Grimm starts 10pm, Tuesday 14 February, W, BT channel 311
