Young couple, Gemma (Imogen Poots) and Tom (Jesse Eisenberg) want to purchase a house. They visit a strange estate agent, Martin, who tells them of a new development called Yonder. Gemma and Tom drive out to look at the development with Martin. All the houses in Yonder are identical, suburban homes; the place is silent, empty and otherworldly. Martin shows the couple around number nine and then vanishes. Gemma and Tom attempt to leave Yonder but become lost at every route and no matter what they try, returns them to number nine. Their physical and emotional well-being takes a toll as they desperately try to escape.
