Now granted, I've not seen the actual film yet. But from what I've gathered through reviews, promotional material, images and the trailer, this looks like it's based on an early 80s comic book, "Le Club des Cinq: Le secret des Templiers" (http://www.bedetheque.com/serie-3295-BD-Club-des-cinq-(Le).html#12609), by Serge Rosenzweig (text) and Bernard Dufossé (drawing).
And as I can't find any mention of Rosenzweig in the credits, are we dealing with plagiarism here?

You are wrong Alexander becuase in the end of the movie
is this standing radarmessure has showed that under the churchfloor in 1 of Bornholms roundchuchs is there a hidden floor that is 10.5 meter long 3 meter high and 2 meter wide Sience I have ask to look under the Churches mange time to see what is in that room but every time it has been declined the ROOm has never been open
so it is not make over the books you talk about and if You know the story about the templeKnight You should know that they have been in denmark as well
No plagianism.
Both the films and the comic book mentioned are inspired by "The Famous Five" by Enid Blyton.
