A desperate woman trapped on a smooth precipice tries to figure out how to keep from plunging into an abyss of certain death. The premise of writer-director Tim Egan’s Curve is simple—with just the right pacing, doses of body horror, and bursts of music—and the end result is almost uncomfortably suspenseful.

Your heart will start racing within the first 30 seconds... especially when you realize those clouds up above sure look like they’re about to burst. There’s also enough ambiguity here that Curve will haunt you long after its final shot.
