Making a life in a new city can be daunting – and that’s even without a shadow lurking in your window.

In Watcher, the forthcoming film from Chloe Okuno, Maika Monroe is Julia, a woman who’s moved to Bucharest with her fiancé (Karl Glusman). Their new apartment comes with an unexpected extra: A neighbor who seems to always be watching Julia. Slowly but surely, Julia becomes unnerved by the stranger’s disturbing presence in other areas of her life. So why is everyone so quick to brush off her concerns? Is he a harmless neighbor? Or a lethal predator?

Watcher opens in theaters nationwide on June 3, and we’re proud to present the first full-length trailer here. Sign up to get notified as soon as tickets are available in your area.
