This follows Emily, a woman who recently suffered from her newborn baby’s death. She takes up running as a coping mechanism, but her husband thinks it’s only a “fetish”. This ends up with a marriage-ending argument, causing Emily to run away to her father’s beach house.
There, she keeps running, befriending some of the residents. One day, she meets Deke, the mechanic for a drawbridge. He tells her about this guy named Pickering, who every summer bring a different “niece” to his house, disappearing for a few months. On the way back from one of her runs, Emily finds Pickering’s house gate ajar, and sees his trunk open. Inside is a blonde woman, one of his “nieces”. There are numerous stab wounds riddling her body. Emily starts to run away, until she gets knocked out.
She wakes up tied to a chair duct taped to the floor inside of Pickering’s house, with him saying that he didn’t plan on killing the blonde, it’s just that she hid a knife in her sock, and promptly starts to beat Emily. He also has a fascination for breasts, too. Kinda weird.
He leaves Emily so he can deal with the corpse, and Emily tries to escape. She uses her leg strength to break the tape, and then bashes heels waist against the corner of his refrigerator in hopes of breaking the chair.
