"Tobi" is mentioned once in the film. Set in June 2012, the film follows a Latino community in Oxnard, California, where a group of high school graduates deal with the demon of a mysterious cult which has "marked" one of them. They document their experiences using basic tools of recording and with clues from the previous films to try to understand what is happening to them. "The Marked Ones" is the last film in the series to feature Katie Featherston. Set in 2013, the film follows the Fleeges, a family of three who, after having relocated to a house in Santa Rosa, California, discover several tapes that show Katie and Kristi in the midst of their initiation ritual to enter a demonic coven 25 years before. The family begins to be haunted by the demon when the daughter, Leila, is targeted as she was born on the same date as Hunter from "Paranormal Activity 2". Along with normal recorders, the family also discovers a unique video recorder that can show supernatural happenings, which they use to record the increasing paranormal activities. On June 2019, Paramount announced that a seventh installment is in development. The seventh film will be released on March 19, 2021. First-time director Oren Peli had been afraid of ghosts his whole life, even fearing the comedy film "Ghostbusters", but intended to channel that fear into something positive and productive. Peli took a year to prepare his own house for shooting, going so far as to repaint the walls, add furniture, put in a carpet, and build a stairwell. In this time, he also did extensive research into paranormal phenomena and demonology, stating, "We wanted to be as truthful as we could be." The decision to make the supernatural entity in the story a demon was a result of the research pointing to the most malevolent and violent entities being "demons". The phenomena in the film take place largely at night—the vulnerability of being asleep, Peli reasoned, taps into a human being's most primal fear, stating, "If something is lurking in your home there's not much you can do about it." Attempting to focus on believability rather than action and gore, Peli chose to shoot the picture with a home video camera. In deciding on a more raw and stationary format (the camera was almost always sitting on a tripod or something else) and eliminating the need for a camera crew, a "higher degree of plausibility" was created for the audience and they were "more invested in the story and the characters".
