When the gates of Hell open and release its prisoners, the dead walk the earth. But they're not interested in devouring the flesh of the living. Instead, there is dirty laundry that needs to be aired, dark secrets to be revealed, secrets that will shake one family to its foundation and send the world into anarchy. For Chad Higgins, life is on the up and up, that is until his mother-in-law returns from the grave and resumes her place in the family, bringing with her a secret that will shake Chad -- and everyone -- to the core. No one in the Higgins household will look at each other the same way again. Thinking the Apocalypse is at hand, Chad's wife, Martha, attempts to save the family from the new evil walking the earth. When the dead won't die and won't be slowed down, their only hope comes from an unlikely source. Who will survive and who will fly On Hell's Wings?
