Just a few short weeks ago, sixteen-year-old Nick Michelson discovered that he was a psychic medium destined to help restless spirits cross over to where they belong. One evening while working after-hours at his high school, an especially frightening ghost of a bloody soldier appears to Nick and attacks him. Nick sets out on a quest to learn who the ghost is and why he is haunting Nick's high school. Using his deck of tarot cards as a tool, he gradually begins to unravel the mystery surrounding the ghost's death.Meanwhile, Nick is experiencing disturbing dreams and visions during which he witnesses, through the eyes of a killer, the brutal mass murder of several of his classmates at his high school. As Nick gets drawn deeper and deeper into a web of mysteries surrounding his nightmares and the ghost of the soldier, he begins to suspect that the two are related - and that the horrific scene from his nightmares is actually a premonition of events that may - or will - come to pass. Nick must solve the riddle of his enigmatic premonitions and race against time to somehow prevent an unknown killer from shooting up his school - and not become the shooter's first victim in the process.
