She strikes up a new friendship with two very different students launching a horrific series of events. A teacher is found dead, apparently having committed suicide, and circumstances that inextricably link both the past and the present, begin to unveil themselves. As the body count rises, the memories of the deaths unleash the echoes of ghosts down the corridors.
