Grimm

Grimm is a drama series inspired by the classic Grimm Brothers' Fairy Tales. After Portland homicide detective Nick Burkhardt (David Giuntoli) discovers he's descended from an elite line of criminal profilers known as "Grimms," he increasingly finds his responsibilities as a detective at odds with his new responsibilities as a Grimm.

SEASON 1
Portland Police detective Nick Burkhardt thinks that he has his life all planned. He is a successful detective, he has a good working relationship with his boss Captain Renard, his partner Hank Griffin, and other officers in the precinct, he has just purchased an engagement ring, and he is planning to ask his girlfriend Juliette Silverton to marry him. All his plans are called into question when he sees an attractive young woman suddenly morph into a hag, a change that nobody else notices. Later that day in the precinct, a man being charged briefly changes into a lizard-like being, and again, no one but him notices. That evening, Nick's aunt, Marie Kessler, visits him and Juliette. Aunt Marie has cancer and does not have long to live, but before she dies, she has something to tell Nick.

SEASON 2
The season starts where the previous one ended: with Nick being reunited with his mother, Kelly Burkhardt. She decides that a lengthy stay would be counter-productive, so she leaves after a few days, taking the Coins of Zakynthos with her to supposedly destroy them.

SEASON 3
Under the effects of the Cracher-Mortel toxin, Nick causes the plane carrying him to Europe to crash, killing Baron Samedi. In his zombie state, Nick kills a man in self-defense before being captured and cured by the rest of the team. A residual effect of the Cracher-Mortel toxin, however, causes Nick's endurance to be increased along with his strength. Another side effect is that while sleeping or when holding his breath, he can appear to be dead, something that scares Juliette on more than one occasion.

SEASON 4
Nick, Juliette, Hank, and Trubel went straight to Nick and Juliette's home from Monroe and Rosalee's wedding after Trubel told them that Captain Renard was shot, despite everyone being in shock that Nick lost his Grimm powers. The FBI got involved because Trubel killed Renard's shooter, Weston Steward, who was a former FBI agent. Trubel was questioned by the FBI, but she was cleared of any charges as they determined she killed Steward in self-defense. One FBI agent, Agent Chavez, figured out that Trubel was a Grimm and kidnapped her to inform her about people who find what she is and what she can do very important, and that they would be very interested in her services.
