In a post-apocalyptic twist, the trailer for I Think We’re Alone Now shows Peter Dinklage completely alone in a town that used to be heavily populated. That is until he is discovered by Grace (Elle Fanning), an interloper whose history and motives are mysterious. And she wants to stay.

Directed by Reed Morano of The Handmaid’s Tale, I Think We’re Alone Now explores the theme of isolation in the face of undesired companionship. Watch the trailer below, and hopefully you won’t be the only one in the theater when the film arrives on September 21, 2018.
