Solitary

The experiment begins with a shocking twist. This season's guests enter Solitary two by two and must fight for their very existence from the moment they arrive.

The remaining eight guests are put to the test - a nearly impossible one with over forty-thousand possible solutions - before they feel the sting of forty excruciating "Flesh Clips" in Val's most painful treatment ever.

The agonizing conclusion of Val's "Flesh Clip" treatment leaves the guests battered and bruised. Their nerves are further tested by dozens of snapping mousetraps.

A shocking showdown sends another guest home forever. And a microscopic message has them all speaking in tongues. Later, they devour a feast of cruel confections that makes one guest's parting a sweet sorrow.

Val's mind games force the guests to question their sanity, and a gruesome test makes animals out of them all. Two guests earn freedom and a trip to "Club Val", while the other three are literally brought to their knees.

Change is good for some guests...and bad for others, as two break down and two bulk-up to win a suffocating test. Then, a new Valphabet teaches them that "P" is for "Painful" and "Q" is for "Quit".

Val's most macabre challenge yet has the final three guests attend their own funeral - they build their own coffins before having to lie in them. Later, Val spins a spine-tingling treatment that leaves two lives cliffhanging in the balance.

The conclusion to Val's relentless experiment begins with one guest falling from grace. The final two go head-to-spinning-head in an "a-maze-ing" test that gives one of them an advantage in the electrifying final treatment.
