Exclusive Clip: 'American Horror Story' Finale

By
American Horror Story has lived up to its name all season, delivering shocks, surprises and flat-out frights in every episode. Will its finale deliver on the momentum that's been building? We've got a sneak peek!
In ET's exclusive clip, an ethereal, back-lit Vivian (Connie Britton) pleads with Ben (Dylan McDermott) to take her newborn son out of the "Murder House," and Violet (Taissa Farmiga) backs her up, stressing that they're in danger every moment they stay.
Check out the clip, and then tune in to American Horror Story Wednesday night at 10 p.m. on FX for the finale!
