A new year is beginning at Lincoln High School and the first on the scene are the custodians who must prepare everything for opening day. This year's staff is divided between long time senior members and a younger staff. Bill is the newest custodian who must adjust to the many personalities of the people as he learns the history and duties of his job. Bill appears too serious and prefers to read rather than mingle with the other custodians. Sarge is the manager of the group and tries to be a breach between his staff and the Headmaster. In addition to the daily schedules, the men find time for periods of recreation during breaks. Big Jim is the oldest and tells many stories about happenings at Lincoln High. Big Jim isn't talking but rumor has it that the school is haunted. What lurks in the corridors of Lincoln High? Can a multi-cultural staff of Custodians supervised by a pompous Headmaster work together to solve the mystery?
