‘Borealis’ Turns a Solar Flare into a Nightmare

A new trailer has arrived for Borealis, a Puerto Rican sci-fi thriller that places personal survival at the centre of a wider societal breakdown. Written, directed and shot by Heixan Robles, the film imagines a world overturned not by war or plague, but by the sudden erasure of human memory.

The premise begins with a solar flare that strips every person of their past in an instant. Names, relationships and identities disappear overnight, leaving society to unravel as people wake into a world they no longer recognise. At the centre of that collapse is Thalía, played by Gretza Merced, who comes to with no understanding of who she is but with one unmistakable clue that points towards the life she has lost: a Caesarean scar that tells her she has a child somewhere.

That discovery drives the film’s central conflict. In a landscape where memory has become useless and social order is rapidly fragmenting, Thalía sets out to find her missing daughter using instinct rather than certainty. Her path crosses with a man who claims to remember everything, introducing the possibility that knowledge itself may now be the most dangerous form of power.

Rather than building its story around spectacle, Borealis appears to focus on the emotional consequences of its central idea. The trailer leans into disorientation and mistrust, presenting a world where even the most basic assumptions about selfhood have broken down. As new hierarchies begin to emerge from the ruins of collective amnesia, the film raises a clear question about what remains of a person when memory has been taken away.

Robles, whose previous credits include work as a cinematographer and editor on films such as The Resort, La última gira and Trail of Ashes, takes on multiple roles behind the camera here, giving Borealis a strong sense of authorship. The film is co-written with Merced, who also leads the cast in what is being positioned as a physically and emotionally grounded performance.

Alongside Merced, the cast includes Jorge Alberti, Ricardo Alvarez and Jose Brocco, with the wider line-up drawing heavily from Puerto Rican talent. That local grounding appears central to the film’s identity, with real locations and controlled visual compositions shaping a story that is high-concept in premise but intimate in execution.

If the film follows through on the tension promised in its first footage, Borealis may prove most effective not as a story about the end of the world, but as one about what survives when the past is no longer there to guide us. We’ll share more news on the release as it comes.
