Is he the lifeless body in the hospital or is he whatever form he finds himself in now? After Adam chooses to live another life so he can return to his soulmate, Mary, he must face several unexpected obstacles. As he receives guidance from his deceased friends, Adam can only hope their help will be enough to overcome the obstacles, and that his love for Mary will be enough to make him endure a different existence than he ever imagined.

Those Left Behind is the story of one man's unexpected journey to a realm between life and death where he must make an agonizing choice whether to live another life or accept his current destiny.
