Watcher

Every time Julia (Maika Monroe) looks across the street, she sees a mysterious stranger (Burn Gorman) staring back at her. In Watcher, we learn that Julia has recently moved to a big city with her loving boyfriend (Karl Glusman). Her eagerness to jump-start her new life is tempered by the increasing unease she feels from the stranger's creepy gaze, as well as news that a serial killer is stalking the city.

In our exclusive clip, Julia becomes alarmed by screams she hears from her next-door neighbor late one night, which prompts her into immediate action. As other neighbors gather, confused, the door is unlocked by the apartment manager, enabling Julia to check things out for herself. What she finds in the shadows only adds to her unease.
