Last week’s episode of Sleepy Hollow was one of the freakiest yet. Kudos to the special effects team; that possessed girl must have kept more than one person awake at night. Because yowie. Quite the lead-up to the two-hour season finale tonight. We’re adding to that, with a synopsis, great trailer, and three clips from the upcoming first hour.

If you’ve been meaning to catch up on all the scares and periodic unexpected laugh-out-loud moments and John Noble and full-on excellence that is Sleepy Hollow, don’t worry. Check out the trailer below, and much will be explained to you.

Then watch the season finale tonight at a special time, 8/7c (Almost Human is off tonight), for the double episode. Then go back and rewatch as much as is available on On Demand, because it really is that good. Plus, it is coming back for a second season, so for those of you who don’t want to “invest” in a show that won’t come back, no worries here.
