As winter approaches, an exclusive Golf Club hires a Multinational biotech whose “revolutionary” fertilizer melts the snow and genetically modifies the grass so its affluent members can play golf all year round. The result is the contamination of the water which ultimately transforms most of the residents into Zombies. One of the few survivors, teenage boy André, watches as the infection rapidly spreads, leaving him alone with his baby sister Annie. Along with Dan, the community security guard and self-proclaimed survivalist, they embark on an adventure that takes them to the source of the contamination. In a race against the clock, they band together to find the cure before everyone they love turns into grass.
