The movie stars Adam Scott (Parks and Recreation) and Taylor Schilling (Orange is the New Black) as couple Alex and Emily who have just settled down in L.A.. Whilst taking their son to the park they meet one of their new neighbours Kurt, played by Jason Schwartzman (Big Eyes), also there with his son. Kurt invites the couple to his house for a dinner party with his wife Charlotte, Judith Godreche (Stoker). Things seem pretty normal until the kids go to bed. After that...well, you'll see in the trailer.
The Overnight is set to release on June 19 in the US, and you can watch the trailer below:
