Cory, Shawn, and Topanga are starting high school. Eric makes them a guide to John Adams High School, on the condition that they don't speak to him during school hours. However, a simple manual does not make Cory's first day perfect, as he quickly runs into the school bullies, led by Harley Keiner. When he accidentally gets Harley into trouble with the new high school principal, Mr. Feeny, it may be both Cory's first and last day of high school.
