Bea (Rose Leslie) and Paul (Harry Treadaway) are newly married and off to have a romantic honeymoon in a rustic cabin set in a secluded forest. During their stay there, they go to a small restaurant where Will, the owner, initially acts hostile and asks them to leave, but later calms down, realizing he was Bea's childhood friend. Will's wife then comes in, acting strangely and saying they need to get away. Afterwards, everything goes normally until their wedded bliss is cut short when Bea goes missing. Paul finds her naked and disoriented in the woods with no evidence as to how she got there or why she was there in the first place. He takes her back to the cabin, where she claims she was sleepwalking due to stress, and tells him to make nothing of it.
