Dorian Leith can see ghosts. Not only that, he listens to their problems and tries to help them move on to the afterlife. It's a gift that's made him an outcast to everyone in town. That is except for his dearly departed grandmother, who he's partnered with to turn this paranormal ability into an honest living, and the local bookshop owner, who seems to be the only non-deceased person willing to give him a chance. But it's all worth it to Dorian, who feels like he's been given a bigger purpose. A chance to save those who cannot save themselves.

Then one day, the key to Death's Door is stolen, trapping all the ghosts in the land of the living. Since he's only one who can see them, the spirits rely on Dorian to retrieve the key before it is too late. If they can't move on, they'll soon be consumed by a ghostly rot that has begun to plague them.

As it continues to fester and spread, and the ghosts become desperate for relief, Dorian must do whatever it takes to find a way to bring peace to the restless dead--even if that peace comes at the cost of his own....
