In INTRUSION, Meera (Freida Pinto) and Henry Parsons (Logan Marshall-Green) have just left Boston to move into their dream home near a small town in New Mexico. Henry, a successful architect, designed the home, and it seems the perfect place for the couple to begin a new life after Meera's recent breast cancer scare. Moved in, Meera resumes her career as a therapist, and the couple seem to be living an ideal life. These illusions are soon shattered when, after a dinner date, Meera and Henry return to find that their home has been broken into and vandalized, with their smartphones and laptop stolen. Meera is traumatized by the robbery, and Henry takes steps to secure the home, including installing a high-tech home security system. While they try to settle back into normalcy, one night while they are sleeping, the home invaders return. They tie up Meera, but after Henry frees her, she learns that Henry keeps a gun hidden in one of her plants, and as she escapes to the car, he kills them. While talking to the police after the home invasion, the investigators tell Henry and Meera that a family of career criminals on the poor side of town were behind the home invasion, and that also the daughter of the family went missing one month ago. As the discovery of the gun has already created an air of mistrust between Meera and Henry, they try to pick up the pieces and move on with their lives. Meera begins to harbor new suspicions. After he forgets his wallet while driving to the store, Meera follows him and discovers that he wasn't actually going to the store. A look at Henry's GPS history reveals other visits to out-of-the-way and very questionable locales. While Henry tries to put Meera's mind at ease, further investigations begin to reveal some ugly truths, and Meera must discover what really happened with the home invasion, and how nothing in her life is what it seems.
