Rosie and Dan are a couple in a doomed relationship. Deciding to call it a day in the least acrimonious way possible, they decide to take one last walk in a favourite destination; the local forest.
However, the endlessly winding paths suddenly lead nowhere, the trees never seem to end, the sun never sets and a sinister presence starts stalking and tormenting them, trying to drive them insane. There is seemingly no escape but what exactly are they hiding from?
