You're just a regular, teen girl in 2005 in US, somewhere. School shootings were a regular thing there, and one happened earlier.

You woke up with a strong headache in a dark, cold room, only laying on a matress. You try and remember what happened but you can't, its hard with this headache. You looked around at your souroundings to try and figure out where you were and why.

Until the door opened on top of the stairs and the light came inside a bit revealing that you were in a basement.
