In Season 27 of "Big Brother," houseguests will spend the summer inside Hotel Mystère, an enigmatic yet luxurious version of the "Big Brother" house.

The long-running reality competition series "Big Brother" officially returns on Thursday, July 10 at 8 p.m. ET on CBS.

The first cheesy segment of the season then occurred: An odd man in a red mask appeared on the TV and said he was behind the disappearances of Julie and the HOH relic. Julie called the houseguests on a phone and told them that eight people would try to find her and the other eight would look for the HOH relic.
