The PARANORMAL ACTIVITY film series continues with this fourth entry from Paramount Pictures and returning directors of the previous outing, Henry Joost and Ariel Schulman. This time, the cell phones and computer cameras are focused on a teenage girl (Kathryn Newton) whose family allow a young boy in their neighborhood named Robbie (Brady Allen) to stay with them while his mom is sick. Soon after, eerie things start happening in the household, some of which focus on the girl's younger brother Wyatt. As the bumps in the night become more pronounced, the mysteries surrounding Robbie's family and the house across the street grow to the point where the only thing for the teen girl to do is investigate herself.
