The houseguest contestants on the CBS summer reality series "Big Brother" will have a saboteur among them.
His or her mission: to carry out viewer suggestions on how to best disrupt the lives of fellow players.
"Big Brother" this season premieres at 8 p.m. July 8. Then, beginning on July 11, episodes will air three nights weekly: Sunday, Wednesday and Thursday.
Viewers will learn the identity of the saboteur in the house on air. Of course, houseguests do not have access to TV or any outside communication while the game is on. Once revealed, viewers will be able to submit suggestions to the saboteur on ways to wreak havoc.
