'Big Brother 17': Final Three Face Off in the Last Head of Household Competition (Exclusive Video)

It's time for Big Brother to crown its latest winner.

Either Liz, Steve or Vanessa will walk away half a million dollars richer.

To get that last chance at the check, they'll have to face off in the first part of the last "Head of Household" competition of the summer. 

In The Hollywood Reporter's exclusive video from Wednesday's season finale, fans can get a first look at what to expect when the final three face off for the last time. In the first part of the HoH competition, the final three are doused in what looks like red candy apple coating. But which apple will rise in this crop and which will end up rotten? "It's hard to keep your balance, it's way more slippery, and this is not going to be easy," says Liz. 

Who will win the first round of the HoH competition and move on to part three? Who will convince the jury that they deserve to win? Who are you rooting for? Sound off in the comments section below and stay tuned to The Live Feed for finale interviews and THR's interviews with the winner, the runner-up and the one who was evicted before the final two. 

Big Brother's season finale airs Wednesday at 9:30 p.m. on CBS.
