Along Came is the story of Michael May, a con-man faith healer with a complicated past plundering his way through every church, chapel, and potluck in the area. Everything changes, however, when his own promises come back to haunt him when out of the backwoods along comes a mentally disturbed man and his actually possessed younger sister. Together, the two outcasts form an unlikely bond as they attempt to escape and survive in the backwoods of Appalachia.
