The performances by Poots and Eisenberg are commendable enough which literally does bring out the best from the script. The set design of the movie does give โfake-but-realโ vibe to the viewers which imparts an idea to the masses watching the movie that Tom and Gemma are indeed trapped in a sick experiment by Martin, their real-estate agent (played by Jonathan Aris).
Martin takes Tom and Gemma to a neighborhood where all the houses are the spitting photocopies of each other, which is rather unsettling to the viewers yet goes unquestioned by wither of our main protagonists. Martin shows around the property no. 9 to the couple and amidst it he disappears, leaving Tom and Gemma behind. Soon the couple discovers that they have been abandoned and are trapped in the neighborhood after having circled around it in an attempt to get out of the place but fail miserably and eventually run out of the fuel.
Their human psyche accepts the situation at the hand soon and began to look for the solutions to this problem, such as writing โHELPโ on the roof as a sign for someone to catch up on but sooner they notice that no aircraft seem to pass by. Not much later in the movie, they receive a box full of groceries and another box with a child in it. This scene brings back the viewers to the point when Martin mentions to the couple that the property is perfect for starting a family and asks Gemma too if they have any kids of their own.
Along with a child in the box, comes an instruction which says โraise the child and be freeโ and by this point of time, the couple has just accepted the reality of the things and move on with it, but does not stop for the ways to escape this hellhole. Certain elements of the writing make the viewers realize that the smallest of the small things such as air we breathe and the food, we consume are not fake such as when Tom expresses his feelings to Gemma how he misses the air used to feel like before this place.
