The show was created by Jim Kouf and David Greenwalt, a pair of producers from Angel investigation Mission. The play is based on the archetypal characters and stories in Grimm's Fairy Tales, and most of the stories and characters in the play come from the characters in the book. Portland police officer Nick Burkhardt (David Junturi David Giuntoli) has just been promoted to a homicide detective and is ready to play a big role in his new job, but he begins to see something terrible that can't be explained by words. Nick's aunt Marie revealed a big secret to Nick, and Nick's life changed. Marie said the ancestors of the Burkhardt family once belonged to a group of hunters whose unified code name was "Green". There are a large number of supernatural creatures in this world, they try to invade the world and destroy mankind, and the task of "Green" is to stop their plot. As Nick learned more about his family background, he became more and more aware of his duty to the Grimm. The Brothers Grimm are fake, but Grimm's fairy tales are true-this new discovery is not only.
