When the 100-year-old Buxley Military Academy falls on hard financial times and is forced to merge with a school for girls, the academy's resident ghosts – General Eulace C. Buxley, Bettina Buxley and Sergeant Major Chester B. Sweet – are aggrieved and aroused from their sleep to seek justice. Outraged by this disrespect of tradition, the spirits are further appalled by a modern world of equal rights for women and rock 'n' roll, as well as the dishonest designs a wealthy matron has for the school. The ghost trio declares war on the living who are involved in their own battle of the sexes.
