Big Brother is one of the longest-running entertainment shows on television, and it’s extending that run when a new season premieres this Wednesday night at 8 p.m. ET on CBS. Season 27 will be known as Big Brother: A Summer of Mystery, and the houseguests will find themselves living in a house dubbed Hotel Mystère which is filled with creepy clues and paraphernalia to keep everyone on their toes. This season will also feature the arrival of a mystery houseguest and a “disruptive” masked visitor. (While Big Brother stands on its own as an addictive reality competition, the moody vibes of Hotel Mystère and this season’s twists are definitely giving some Traitors energy…)

Here’s everything you need to know to tune in to Big Brother when season 27 premieres this week!
