"Part One: The Prisoner"

Gary is a troubled actor who is wearing a green bracelet on his wrist, under house arrest living in another person's house because he burned down his own. The owner of the house is described as a TV writer away on work. While living in the house, he is befriended by both a P.R. "handler", Margaret, and the single mom next door, Sarah, who may or may not be interested in him romantically. Over the course of his house arrest, Gary becomes convinced that he is being haunted by the number nine, including finding a note in his own handwriting saying "Look for the nines". He encounters many occurrences of the number nine: while playing backgammon, he rolls nines; while reading newspaper advertisements, he becomes obsessed with finding nines. Asking Sarah about the number 9 worries her, and she cryptically tells him: "I can get you out of here". He sees different versions of himself around the house, which unsettles him, causing him to break out of his house arrest barrier which in turn destroys reality in a blinding flash.

"Part Two: Reality Television"

A television writer Gavin is trying to get his pilot produced. He leaves home to work on his TV show, Knowing, about a mother and daughter who are lost, which stars his friend Melissa McCarthy as the lead actress. In a conversation about reviews and critics Susan, a television executive and producer of the show, tells Gavin to look for the nines, which he then writes on a piece of paper, the same piece that Gary found in Part One. He also tells Melissa that he thinks he is haunted by himself. During the process of post-production, Susan pushes for Gavin to ditch his friend Melissa as the unconventional lead of his project in favor of a more attractive, well-known actress. This causes an argument between him and Melissa. He then finds out that the well-known actress was actually cast in another show, which Susan knew before suggesting her. Since the well-known actress is now unavailable, and Melissa won't answer Gavin's calls, he confronts Susan about her knowing that his show would never get picked up and about him only being a subject on a reality television show. After a heated exchange, he snaps and slaps her. Seemingly insulting his manhood for hitting a woman, she scoffs: "Do you feel like a man?" and walks away, which leads to him telling the reality TV cameraman to leave him alone. A pedestrian then asks him to whom he is talking, and it is shown that the reality television cameraman does not exist. He looks around and notices that everyone has a "7" floating above their heads and also that he has a "9" floating above his own.

A flashback shows Gary's P.R. handler, Margaret, telling him that he is God, a nine like the angels, and humans are sevens (koalas, incidentally, are eights because they control weather). He created the world and can destroy it with a single thought. He exists in many different forms and that none of them are real. Gary does not believe this and becomes distraught, which is revealed to be the real reason for his breaking his house arrest barrier.

"Part Three: Knowing"

Acclaimed video game designer Gabriel, whose car breaks down in the middle of nowhere, leaves his wife, Mary, and young daughter, Noelle, to try to get a better signal on his phone. He meets a woman, Sierra, who leads him off into the woods to her car, so she can give him a lift to the gas station. Meanwhile, back at the car Noelle watches a video on a digital camera showing Gavin talking to Melissa from Part Two and Margaret talking to Gary in Part One. She is confused and shows her mom, who appears confused as well.

Meanwhile, Gabriel becomes ill because Sierra has drugged his water with GHB. In all of the stories, as Sarah, Sierra and Susan, she has been trying to separate him from Mary/Melissa/Margaret and make him realize that none of these lives are real. She says that this is an intervention, and she and the other recurring characters have been trying to help him remember that he is not human, but God, who has absorbed himself in various human incarnations for 4000 years. She likens Gabriel's addiction to video game addiction. He is needed back home, a place that cannot be imagined with human thoughts or described in human words.

Gabriel returns to the car and the family goes home. Mary deduces that Gabriel has remembered his reality and needs to leave. Gabriel tells her that there were ninety different variations of the universe, and this is the last one. Gabriel removes the green string from his wrist and the universe morphs into something else. The film ends with Melissa McCarthy's character married to Ben, to whom she had been married in Part Two, with Noelle as their daughter. Noelle tells her mother that "He's not coming back" and that "He put all the pieces together", and her mother finishes her sentence that this is "the best of all possible worlds."
