Overview: It's the most explosive episode yet as the five remaining actresses put it all on the line for a life-changing role in SAW 3D. The girls must learn to act with "nothing" in challenges that put them face-to-face with a deadly monster on a green screen and with an invisible ghost that tosses them across a room like a ragdoll. Sierra commits the worst sin an aspiring Scream Queen can make, while Christine makes a decision that could destroy a friendship. Later, tensions that have been building for weeks between Gabby and Tai finally erupt.
