The Lost Treasure of the Knights Templar

Katrine, aged 12, spends her vacation every year on the Danish island of Bornholm and through the years she has found a close friend in the island priest Johannes. She has also spent the summers hanging out with her friends Mathias, Nis and Fie. But this year things are going to be different. Nis has stumbled upon a book claiming that the round churches of Bornholm have been built by the Knights Templar in the 1100s. And combined, the round churches will form a series of geometric shapes that can be seen as a treasure map. A treasure map that might reveal the secret location of the mysterious treasure of the Knights Templar. A treasure that has been gone since 1307.

At the same time, strange events take place around the island. The kids witness men dressed in black robes, The Black Brotherhood, performing some kind of ritual. And in the middle of the ritual, the old priest, Johannes, is pushed off a cliff into his death. The kids decide to solve the murder case. They are convinced that there is a link between Johannes´ tragic death and the treasure, and therefore they commence a thrilling treasure hunt in which one clue leads to the next. Soon they realize that The Black Fraternity is also looking for the treasure. Following a terrifying escape from the black hooded men the kids wind up in Østerlars round church – the place to where all the clues lead. Here they find a hidden entrance to a crypt below the church. A crypt that guards an incredible secret. But The Black Brotherhood also locates the crypt and they carry a trump. A final, gruelling battle will take place, and the kids will find help in places they never thought to look. (official distributor synopsis)
