One brother races against time to save the other before it's too late. When Matt has a dream, it sends two brothers on a hunt for a cave. Matt doesn't know why they have to go there; he just knows they have to go. When they arrive, Matt finds out that the vision turns out to be a trap. A Darkness like no other wants to control Matt and kill Zack. When a demon asks Zack a question, "How far will you go to save your brother," Zack replies, "As far as I have to." Now something like they've never faced before is on a deadly mission to destroy everything the brothers hold dear and if they are not careful, neither of them will be able to escape.
