Dr. Martin Sanders is a young doctor who just landed his first job. He lives in Baltimore, Maryland, and the job is in Franklin, Tennessee. The new job is in a small town at a clinic that for some reason cannot keep a doctor on staff, as every doctor leaves abruptly and goes missing. Sanders is determined to make the most out of his position there and to be the doctor ongoing for the clinic; however, on his travels to the town, he has a run of bad luck, and his car breaks down. Although he receives help from the townspeople, they are very quiet about the previous doctors and their disappearances. The more questions he asks, the more silent the town folk become.

Thinking this to be just because he is a Yankee, he starts his job with hope and works until his fourth month at the clinic. Dr. Martin Sanders notices an old painting on the wall of the office, daily, that just doesn't look like it belongs, and one day he decides to take a closer look. He falls into the painting, dropping him into another world, a clinic seemingly like his own, only it is heaven. The town from which he came in Tennessee is purgatory. After serving his time there, he has a higher calling, but he isn't the only person there. Every doctor that went missing is there too, even his mother.
