The theme of the summer is the BB Time Trip, sending Houseguests on a journey unlike anything ever seen before–from prehistoric times to iconic decades and unforgettable moments from Big Brother history.

A time-warping new season of Big Brother begins as 14 new houseguests turn back time and collide with the past's greatest reality legends in three era-spanning competitions. Then, tragedy strikes in the Jurassic Period and a houseguest meets their untimely demise.

A new season of Big Brother: Unlocked kicks off with hosts Taylor Hale and Derrick Levasseur dishing all the never-before seen drama from the Big Brother 28 house, joined by new co-host Jerry O'Connell! Then, BB legend Rachel Reilly tells-all about her experience meeting the new houseguests and everyone makes their predictions for the upcoming season.

The first Head of Household of BB28 will be crowned! And the first three nominees of the summer will hit the block. Plus, is it showmance o'clock already?
