Ethan's nerd-fest Halloween party takes a turn for the dangerous when Rory's magical mask transforms guests into the real-life versions of their costumes. Ethan, Benny and Sarah have until midnight to reverse the spell, or the transformations will be permanent.

Oh… and Ethan's Mom comes home early from her own party, with a witch costume that's very convincing…
