The First Strike

This is a fanfic story based on the scream movies.
I think that's pretty self-explanatory.
this will probably not fully comlute with the actual scream movies, just bare with me.

A couple of girls, all friends, have a normal fun, happy life. Until one party, someone in a mask came and attacked everyone, one person was killed and 2 others were injured. they didn't know who did it because they had a mask on. who did it? are they safe? and why are these issues suddenly now happening only in the spaces they're in? will they lose a friend, or will they all make it out alive?
