As a child, Kate was terrified of the Yard, a sprawling reclamation and resale business owned by her father. She hated its toy sheds full of beady-eyed dolls and especially its hall of mirrors. When her father, suffering from dementia, physically abuses her mother and leaves to live in the Yard, her family tasks her with retrieving him. Her father says he'll only return home if Kate polishes every mirror in the hall, so she begrudgingly hides her fear and begins the tasks.
As Kate works with the mirrors, she realizes a creature lives within them, a monster desperate to emerge from the glass. Her father's decision to live at the Yard may not be to escape her mother, but to stop a supernatural being from getting loose. Kate waits until the monster emerges and smashes it with a broom. It seeps into the bag of old rags her father calls "Ragman."
Kate's father tells her he's never coming home; he can't bear his marriage and prefers the solitude of his business. She leaves, disturbed by her father's final decision - to put Ragman in his office so he has some company.
