The first of four new weird tales from Hawkins, Indiana-A small town that keeps getting stranger. After shaking off a mysterious encounter with a strange "dog" while out at the Drive-In Cinema, Hawkins science teacher Scott Clarke is inspired to teach his students all about how 3D glasses work and it spirals into theories about alternate dimensions and how they might be perceived. Dustin keeps secret that the weird "dog" could be nothing other than Dart, his missing pet demodog.
