In episode 11 of "Grimm" season 5, Nick and Monroe visit a church in hope to find clues indicated in the map.

With five out of the seven mysterious keys now in Nick's possession, the team is going all out to find out where the mysterious treasure could be. When the five keys' markings were fitted together, they compare the drawings from an actual map and compare to find what places could be indicated in it. Monroe declares that it looks like they were going on a crusade to determine which of the churches in the area the keys could be pointing at.

Hollywood Hills shares the episode synopsis, which says: "A trip overseas will take Nick and Monroe on a dangerous journey. Newly gained artifacts are going to take Nick and Monroe closer to the source of a long-gestating mystery. Elsewhere, Black Claw is going to make a deadly move that will send Portland into disarray."

Photos from the upcoming episodes show Nick and Monroe at night time in the forest. In the "Map of the Seven Knights," they have identified Black Forest from the location indicated in the map. Back in Portland, Captain Renard is shown supporting his mayoralty candidate, Andrew Dixon, at a political rally. There is also a photo of a seemingly disappointed Hank and Drew among the candidate's supporters. A priest and two other men were pictured inside a church.

The preview trailer focuses on Nick and Monroe's stop over to a chuch. It is revealed that the priest is a wesen and that one of his men is waiting with a gun inside the church. The voice over in the background says, "The further they get from home, the closer they get to evil."

It also looks like Hadrian's Wall is gearing up again for a big fight as photos of their leader Lucien Petrovich is also seen. And it looks like another character will figure in the mystery as Deadline reports that actor Shaun Toub has been recently been cast to play a recurring role. According to the news, he will play a character named Bonaparte who abides by history but does not necessarily act as a villain.

The series is nearing its 100th episode and viewers will have to wait a little more as the next episode will be shown on March 4.
