Isa

Isa Reyes, just about to graduate high school and begin studying computer science, is struck by a car and rushed to the hospital. Doctors discover a foreign object in her brain that gives off a radio signal, hinting at a larger mystery. The accident marks the beginning of a series of unexplained medical and technological oddities.

That night, Isa dreams she is being driven home by her deceased parents. Her mother tells her there was no accident. She wakes inside the dream and breaks into a vault to find a golden cocoon.

Two engineers in Mexico interpret Isa's dream as a break-in and reboot their monitoring system from afar. Isa wakes up in pain, still clutching the cocoon, as the remote action affects her body. The incident reveals a hidden network connecting her brain device to something much larger.

A female scientist reports the break-in to a shadowy banker and promises to retrieve the chip used. She dispatches Borroso to track down the people Isa mentioned in her dream. The banker views Isa’s chip as a highly valuable asset that could be exploited.

Borroso visits Isa's school and shows a doctored evoked potential video intended for implanted chip wearers. Isa’s dream-state activates when the test triggers her chip, linking her unconscious activity to the scientist’s system. The scientist observes Isa’s mind and begins tracing her past.

In the dream, Isa follows a monarch butterfly back toward Mexico and learns more about her true history. The scientist concludes Isa was stolen from a lab as a child, and that her chip has grown into a powerful and lucrative tool for the banker. These revelations tie her fate to a hidden origin and migrant networks.

After finding a photograph from her latest dream on her phone, Isa confronts her adoptive aunt and uncle, who confess they are not related. They reveal she was smuggled into the United States as an infant by unknown migrants. The truth drives Isa to run away toward her real home in Michoacán.

Believing the dream's coordinates point to her real home, Isa resolves to flee toward Michoacán, Mexico. Borroso pursues her, closing in as she travels toward her origins. The pursuit raises the stakes and heightens the danger of her escape.

Borroso kidnaps Isa and plugs a cable into her head, allowing the scientist to download the evolved software by forcing her to relive her worst nightmare. The forced nightmare sequence tests Isa’s resolve and pushes her to the brink.

Isa confronts the nightmare by interpreting it as a vision of her father rescuing her from the scientist’s lab and sending her off with migrants. This insight breaks the hold of the download and buys her time to resist.

Isa wakes in Borroso's lair and disorients him by materializing a swarm of hundreds of monarch butterflies. Her friends Eric and Sabi help her escape as the scientist’s plan collapses in the wake of Isa's attack on their computer system.

The banker punishes the scientist for Isa's attack on their system, which triggers a disruption in the stock market. Isa and her allies slip away, and the conspiracy loses a key asset as the balance of power shifts.
