New library employee Margaret (Blythe Danner) works late at night and does her job well. However after a while she becomes nervous and scared because she reads reports of a serial killer that already murdered seven people and when her boss one night leaves for getting a sandwich, Margaret thinks that she is left alone in the library with the serial killer running around.
This episode wasn't that special for me but in the end I liked it because I found the twist very unexpected. Not a must see but still good.
