When the ghost of a Civil War soldier, killed visiting his sweetheart across enemy lines, comes back to haunt the Virginian locals at an old mine, Rick Brant and his ex-marine colleague Scotty decide to investigate. Curiously, the ghost always appears at exactly 9pm, and even then only when there is a considerable audience. Rick, as keen to debunk the unscientific supernatural fears of his younger sister as he is to solve the mystery itself, uses courage and the scientific method to unmask the inevitably human face behind the ghostly blue apparition.
