Set in Boston in 1978, a meeting in a deserted warehouse between two gangs turns into a shoot-out and a game of survival.

During the Civil War in 17th-Century England, a small group of deserters flee from a raging battle through an overgrown field. They are captured by an alchemist, who forces the group to aid him in his search to find a hidden treasure that he believes is buried in the field. Crossing a vast mushroom circle, which provides their first meal, the group quickly descend into a chaos of arguments, fighting and paranoia, and, as it becomes clear that the treasure might be something other than gold, they slowly become victim to the terrifying energies trapped inside the field.

As a deadly virus ravages the world, Dr. Martin Lowery embarks on a mission to reach test site ATU327A, a research hub deep in the Arboreal Forest. The arduous journey, guided by park scout Alma, is set back by a nighttime attack that leaves the two bruised and shoeless. When they run into Zach, a man living off the grid, they gratefully accept his help. Zach’s intentions aren’t exactly what they seem, however, and a path out of the forest and into safety quickly fades as the line between myth and science blurs.
