Big Brother

Seasoned host Julie Chen Moonves returns to helm the 27th season of the reality competition. In this combination of a reality series and a game show, the contestants battle it out each week to maintain their places in the house, all in the hope of claiming the $750,000 prize awarded at the end of the summer. This season's theme for the reality show is "A Summer of Mystery," where the house is transformed into a suspense-filled hotel, complete with secrets, hidden passageways and a mysterious vibe that sets the stage for a summer of intrigue.
