When twenty-three-year-old master's student Tadhg Kelly joins his twin brother and his girlfriend on their getaway to a cabin in rural Ireland, he hopes to escape all of the drama that's been destroying his life. He wants to forget about his thesis deadline and the terrible, never-ending bad news that fills the headlines. Most of all, he wants to forget about his cheating boyfriend.

But Tadhg soon finds much more than a mere cheating scandal to worry about.

As soon as the trio enter the eerie village of Killimercy, odd things begin to happen: a strange man peering into the window of their cabin; a mysterious break in, and a unique Celtic symbol haunting Tadhg wherever he goes.

Just as they ready themselves to flee, things only get worse...
