Boreal

After the death of their son in a car accident, Ana and Pablo move to the mountains to open a country house, where they're joined by friends Guille and Bea for an opening dinner. A strange aurora borealis isolates them, during which Guille suffers a mysterious attack that severely injures another person and tells an alternate version of their lives - one in which he's Ana's partner, not Pablo's, with their son still alive. As reality begins to unravel, the group starts to question what is real and what is just Guille's fevered imagination.
