Grad '68

With nothing better to do, Karen begins going through cold cases and soon attempts to find out who spray-painted "Grad '68" on the town's water tower, a Dog River mystery that has remained unsolved for many years. Meanwhile, Lacey's idea of putting the ancient Roman symbols for male and female on the bathroom doors confuses many into going through the wrong doors. Many of the men who see how beautiful the women's bathroom is are upset when Brent puts the old signs back on the doors. (imdb)
