The Big Brother houseguests will be heading out on a time-traveling adventure this season.

Big Brother: Time Trip will be the Season 28 theme, turning time into the ultimate twist.

Houseguests will enter a world where rooms, relics and competitions transport them across moments in time, while early twists shake up the game from the start.

Inspired by decades like the ’80s and Y2K, new powers and challenges can disrupt strategy and alliances.

It has also been revealed Big Brother: Unlocked will premiere with a new interactive fan vote that will have a major impact on the game.

Big Brother will return to Global TV on Thursday, July 9th.

That debut episode will be 90 minutes long ((8:00–9:30 PM, ET/PT).

That will be followed by the return of Big Brother Unlocked on Friday, July 10 (8:00-9:00 PM, ET/PT) and a 90-minute Sunday episode on Sunday, July 12 (8:00-9:30 PM, ET/PT).

Julie Chen Moonves will return for its 28th season as the host and Paramount+ subscribers and Pluto TV viewers can catch all the action inside the hours with the Big Brother Live Feeds.

After the premiere, the series will air Wednesdays (8:00-9:30 PM, ET/delayed PT), followed by hour-long shows on Thursdays, featuring live evictions, and Sundays (8:00-9:00 PM, ET/delayed PT).

Here is a look inside the season 28 house.
