Higurashi No Naku Koro Ni?

I was browsing on Youtube when I came across an anime called Higurashi No Naku Koro Ni (translates literally to When Cicadas Cry or When They Cry). I am not entirely sure what the story line is but I do know that it is one of the scariest shows that I have ever seen: All of the scenes that I've seen so far consist of one girl brutally murdering all of the characters. And I thought Death Note was scary. I think I may watch this if I have time, I still need to finish Lucky Star, Haruhi Suzumiya and Fruits Basket.
