Plainfield high School was the high school that graduated all four founding members of Overman, Russell Eggenberger, Matthew Radowski, Aaron Kelly, and Nick Huditz.
The original building was completely destroyed by one of the worst tornadoes in Illinois history. The Plainfield Tornado struck the town on August 28, 1990, one day before classes were scheduled to begin. Three faculty and staff members lost their lives, but had school been in session, casualties would have been more significant as the tornado hit the school directly.
In the middle of the 1992-3 school year students moved into the new PHS building. At the time, it was one of the most technically advanced high schools in the state of Illinois, complete with its own observatory. In 1998, the school added a "freshman center" with its own gymnasium and cafeteria. The new freshman center has three floors and is connected to the main building by an enclosed catwalk.
Russell, Matt, Aaron, and Nick all successfully graduated in 1999. Since then the place has gone to hell.
Optimus Prime, a protoOverman, was included in the roster of the Plainfield High School Battle of the Bands in 1998
