Grimm is an American occult detective police procedural drama series. It debuted in the U.S. on NBC on October 28, 2011. The show has been described as "a cop drama—with a twist... a dark and fantastical project about a world in which characters inspired by Grimms' Fairy Tales exist", although the stories and characters inspiring the show are also drawn from other sources.

On April 5, 2016 NBC renewed Grimm for a sixth season, consisting of 13 episodes. On August 29, 2016, NBC announced season 6 would be the final season and that it will premiere on January 6, 2017.

Synopsis:

Homicide investigator Nick Burkhardt of the Portland Police Department learns he is descended from a line of guardians known as Grimms, charged with keeping balance between humanity and the mythological creatures of the world called Wesen, the German word for being or creature. Throughout the series, he must battle against an assortment of dangerous creatures, with help from his Wesen friend, Monroe, and his partner, Detective Hank Griffin.

Opening: "There once was a man who lived a life so strange, it had to be true. Only he could see what no one else can—the darkness inside...the real monster within...and he's the one who must stop them. This is his calling. This is his duty. This is the life of a Grimm."

Cast and characters:

David Giuntoli as Nicholas "Nick" Burkhardt, the eponymous Grimm. Nick is a Homicide detective, whose Aunt Marie (Kate Burton) tells him that he is descended from a line of hunters, called Grimms, who fight supernatural forces. Even before his abilities manifested, Nick had an exceptional ability to make quick and accurate deductions about the motivations and pasts of individuals, which has now expressed itself as his ability to perceive aspects of the supernatural that nobody else can see. He temporarily lost his Grimm power after the event of season 3 finale through a revenge scheme by Adalind, but regained them in the season 4 episode "Highway of Tears". He later learns that Adalind is carrying his child, which was revealed to be a boy, whom Adalind named "Kelly" after Nick's mother (Mary Elizabeth Mastrantonio).

Russell Hornsby as Hank Griffin, Nick's Homicide partner, who is not aware that Nick is a Grimm until Episode 3 of Season 2. He is somewhat sarcastic at times and has gone through at least four marriages by the time the series begins; nevertheless, he is Nick's best friend in the human world, becoming closer once again after Nick revealed the truth about his Grimm heritage and the Wesen out in the world.

Bitsie Tulloch as Juliette Silverton (Seasons 1–4) and Eve (season 5), Nick's girlfriend, a veterinarian. She was originally unaware of Nick's duties as a Grimm until he tells her in the finale of Season 1. However, by Season 2, a magically induced amnesia removes Nick from her memory altogether, to the extent that she only forgets Nick while still remembering characters like Monroe when she only met him through Nick. Although Nick's Aunt Marie suggested that he leave Juliette for her safety, Nick decided to stay with her. He postponed his original plans to propose to her while he explores his new life as a Grimm. She eventually regained her memories and learned the truth of Nick's abilities, joining him in dealing with some Wesen-related problems, such as finding a cure for a disease that gave human children the appearance of Wesen. In Season 4, a series of events and dangerous spells results in Juliette becoming an exceptionally powerful Hexenbiest, and her personality becomes drastically more antagonistic and less empathetic as a result, enjoying her power while disregarding her friends' concerns, her attitude conflicting between reveling in her power and hating Nick's allies for doing this to her. After her plans for revenge culminate in the death of Nick's mother, she is shot with a crossbow by Trubel in the Season 4 finale. In season 5, Tulloch plays "Eve" a mysterious woman who has all of Juliette’s memories and powers, but none of her emotional attachments.

Silas Weir Mitchell as Monroe, a wolf-like creature called a Blutbad who aids Nick with his cases. He is also a good friend of Nick's, even though he has some issues with Grimms since a Grimm killed his grandfather (but he acknowledges that the ancestor deserved it for butchering a village). Monroe is knowledgeable about many of the wesen that Nick goes up against, serving as Nick's direct source of insight and information into the supernatural community whenever the second-hand knowledge that Nick acquires from his ancestors' books is inadequate, as well as assisting Nick when cases require Nick to rely on someone who knows about the threats he faces. He also helps Nick make contact with creatures that would avoid Nick due to his status as a Grimm. Eventually, Monroe fell in love with and married Rosalee, despite facing some hostility from a Wesen cult focused on purity due to their mixed heritage.

Sasha Roiz as Captain Sean Renard, a fluent francophone; Nick's adept and efficient superior. Renard is a magical creature called Zauberbiest and royal bastard. His mother Elizabeth (Louise Lombard) is a Hexenbiest, a witch; and his father is a Royal, a fact of which Nick was not aware until the middle of Season 2. He is also the father of Hexenbiest Adalind Schade's daughter Diana. In Season Five he was manipulated into running for mayor as part of a plan by pro-Wesen organization Black Claw, who seek to put Wesen in a position of power over humans rather than hiding among them.

Reggie Lee as Sergeant Drew Wu, a police sergeant who works with Nick and Hank; he tends to do the "grunt work" for them, running down facts and information. In Episode 9 (at the beginning) of Season 4, Nick was forced to tell him everything about the Wesen world after he started losing his mind due to all the "Wesen" involved murder cases. Since then he has been a loyal member of Nick's team, providing an additional hand in the field.

Bree Turner as Rosalee Calvert (Recurring season 1; Regular season 2–present), a fox-like creature called Fuchsbau who takes over her brother's Wesen spice shop after he is murdered. Rosalee assists Nick and Monroe in their efforts by providing more information and remedies to supernatural problems, such as helping him extract a golden 'tumor' from a bird-like Wesen or developing a cure for Nick's Wesen-induced blindness. She married Monroe in the Season 3 finale. She revealed she was pregnant in the season 5 finale.

Claire Coffee as Adalind Schade (Recurring season 1; Regular season 2–present), a witch-like wesen called a Hexenbiest who was working for Renard and who after ingesting Nick's blood, became a normal human being. Seeking revenge, she poisoned Juliette to forget all memories of Nick and started colluding with Renard's half-brother, Eric, eventually regaining her powers through agonizing rituals. She had a daughter with Sean, Diana Schade-Renard, who has unique powers. She recently gave birth from an emergency c-section to her second child, a boy she named Kelly (after Kelly Burkhardt), whose father was revealed to be Nick as she slept with him during a complex ritual to take his powers that involved her disguising herself as Juliette. After Juliette was transformed into Eve, Adaline moved in with Nick to care for Kelly, the two even forming a relationship, but this was complicated by the Royals' attempts to use Diana to improve Renard's image in his mayoral campaign.
