Alysa is a 17 years old girl which still goes into school. She lives in a small village but there's a big school. The building has 3 floors and a glad roof with plants there. But a virus broked out a few years ago and all the people behave strange, like zombies, but they are fast. Alysa didn't see any real human a long time. She walks to the school to have this as a shield. "Finally...I'm there."
