In the seemingly idyllic setting of a wealthy gated community, an ordinary agricultural product takes a terrifying turn. A common fertilizer, intended to nurture lush gardens and manicured lawns, becomes the catalyst for a sinister genetic mutation. This mutation rapidly spreads among the residents, transforming them into mindless zombies. The once peaceful enclave quickly descends into chaos as the infected lose their humanity and pose a dire threat to anyone nearby.
Amidst this growing horror, the community is quarantined, turning the entire island into a perilous prison with no easy escape. The authorities cordon off the area, hoping to contain the outbreak, but this isolation only deepens the residents' desperation. The infected roam freely, and survival becomes an uncertain game of evasion and endurance. The lush landscape that was once a symbol of privilege now hides dangers at every turn.
At the heart of this nightmare are a resourceful teenager and his baby sister, whose bond and determination drive the story forward. Together, they navigate the treacherous environment, seeking a way off the quarantined island before the mutation overtakes them too. Their struggle is not only against external threats but also against the creeping transformation within, as time ticks down to the moment they might literally turn into grass.
