Vivarium
A young couple, Gemma and Tom, visit a mysterious real estate agent, Martin, who shows them a house in a new, uncanny suburban development called Yonder. Upon arriving at house #9, Martin disappears, and they find themselves unable to leave the identical, labyrinthine streets of Yonder. Attempts to escape lead them back to house #9, and their calls for help go unanswered. A baby delivery box appears with a child inside, and an attached note instructs them to raise "the child" to be released. The boy grows at an unnatural rate, mimicking their voices and habits in an unsettling way, becoming increasingly demanding and alien. As Tom obsessively tries to dig a hole in the backyard to escape, and Gemma struggles to connect with or control the boy, their sanity deteriorates. The boy eventually forces them to take on his own strange, guttural language and observes their failing health, ultimately trapping them in a horrifying, cyclical existence within Yonder.
