Giovana and Yago cross paths and share a fleeting moment of intimacy, but their lives take a dramatic turn when a mysterious and deadly pink cloud triggers a shelter-in-place order. Suddenly forced to isolate together, they navigate this unexpected lockdown while relying on their phones and video chats to connect with loved ones. During one of these calls, Giovana reveals to her mother that she met Yago just the day before. Compounding their isolation, Giovana's friend is trapped alone, her partner having gone to a bakery, while Yago's father, possibly suffering from dementia, is quarantined with his nurse, who is now gone. Meanwhile, Giovana's younger sister is stuck at a sleepover, cut off from her family.
As days turn into weeks, the strain of their situation becomes apparent. Giovana’s sister shares that her friend's family is rationing food. In response to the crisis, the government establishes a tube system and drones for delivering supplies, allowing a semblance of a capitalist economy to thrive even under these dire circumstances. To cope with their confinement, Giovana, a web developer, helps Yago meet his financial obligations, including his father's nurse's salary, as Yago struggles to work as a chiropractor.
What begins as a mostly platonic relationship slowly evolves into something more passionate. Despite revealing her reluctance to have children, Giovana becomes unexpectedly pregnant and eventually gives birth to a son, Lino, with a doctor guiding the delivery through video chat. Lino celebrates several birthdays within the walls of their home, while Giovana grapples with her mental health, feeling that Yago is oblivious to the gravity of their situation. As she follows the updates on the pink cloud, Yago adopts a stance that hovers between denial and radical acceptance. Their attempts to deepen their bond falter, leading Giovana to express her desire for separation. They end up living apart within their shared home, existing on different floors, with Lino alternating between them every three days, rarely sharing meaningful moments together.
Meanwhile, Giovana's friend, who has been holed up alone for years, faces severe depression, leading her doctor to prescribe antidepressants and motivating her to purchase a robotic dog for companionship. Giovana's teenage sister, still away at the sleepover, brings disturbing news that two of her friends are expecting, while one is being exploited by her partner. Distressed, Giovana offers to send them contraceptives, highlighting the gravity of their youth's circumstances.
Yago's father experiences a downward spiral due to illness and neglects his medication after his nurse's untimely death. Yago is left traumatized and confounded by his father's diminishing recognition of him, suspecting that he could have played a role in the nurse's demise. As Lino grows up, unaware of the world outside, he surprisingly perceives the pink cloud as a curiosity rather than a threat. This innocent view inspires Yago to embrace a religion linked to the pink cloud, including wearing a pink rope around his neck, ultimately coming to terms with their life in isolation.
As time passes, Yago initiates a virtual romantic encounter while Giovana finds solace in "window sex" with a neighbor. Eventually, they rekindle their relationship and recommit to family life. Lino and Yago present Giovana with a virtual reality headset, which she quickly becomes addicted to, spending endless hours immersed in a simulated beach until Lino accidentally destroys it.
A flicker of hope emerges when a mysterious green cloud takes the place of the pink one, prompting Giovana to believe that freedom might be on the horizon. In her excitement, she packs her belongings and eagerly speaks with friends about their long-awaited reunion. However, just when normalcy seems attainable, the green cloud vanishes, giving way to the return of the ominous pink cloud.
Determined to face the uncertainty, Giovana steps onto the balcony, counts to ten, and the scene fades, leaving her fate—amid the ever-present pink cloud—hanging in the balance.
