With its fragile and otherworldly yet rugged and unforgiving landscape, Antarctica has captured the imagination of humanity for generations. In Nightfall on GAiA, director Juan Francisco Salazar frames an exploration of this vast and wild continent as a view into the past from a desolate future. A fictional scientist, stranded alone in an Antarctic research station 30 years into the future, guides the audience on a journey through archival footage of early Antarctic exploration and live footage captured in the Antarctic Peninsula in recent years. Her poetic, contemplative narration through diary entries introduces us to a continent on the edge, and a species at a tipping point.
