Two children, Ian and Clare, move into a town where their grandfather has just died. Ian thinks his grandfather's spirit is trying to tell them something, finding some library news clippings about a man named Zachariah Kull, who was accused of burning his home with his wife in it. Later, Ian and Clare capture a ghost named Jumper (a dead skydiver) who ends up freed by his partner, Coffin Ed (a revolutionary soldier). They follow them and other ghostly wisps of air into the forest, where they find an abandoned building. Entering, they find arriving ghosts entering a mirror, which leads to the afterlife. Ed and Jumper's boss, Mariah (a dead bride) isn't too pleased with this. Ian and Clare learn that they look for souls that don't want to cross over, and are dubbed the "Soul Patrol" by Jumper; they ended up with these jobs while waiting for their turn to cross over.
