cecilia and her young son martin are on a road trip through rural argentina. she has not told him the real reason they left home: they are running from her abusive ex, his father. then a truck hits them. cecilia wakes up three days later on a stranger’s porch with no memory of what happened and no sign of her son.
the film follows her as she tries to piece together the missing days. the police are suspicious. the doctors cannot explain her condition. a religious fanatic named enrique is hunting her, convinced she is something other than human. to him, cecilia is not a victim. she is the enemy.
what makes on the 3rd day work is its restraint. most of the violence happens offscreen. the horror is in the waiting, in the slow realization that enrique is not crazy in the way horror movie villains are usually crazy. he is methodical. he has scripture on his side. he has been preparing for this his whole life. the film knows that the scariest monster is a man who has no doubt.
the mystery is not as clever as it thinks it is. astute viewers will figure out where the story is going before the characters do. but the filmmaking itself is strong enough to carry the weight. daniel de la vega shoots every frame like a painting, all deep blues and blood reds and shafts of light cutting through darkness. the score is sweeping and liturgical. mariana anghileri as cecilia holds the center with a performance that is all frayed nerves and desperate love.
this is not a crowd-pleaser. it is slow and sad and deeply catholic in its imagery. but for a certain kind of horror fan, the kind who prefers dread to jumpscares and atmosphere to body count, it is a minor gem. the library dvd with the generic cover does not do it justice.
