In a quiet high school, the lives of the students take a chilling turn when a new scientific experiment begins transforming some of them into bloodthirsty zombies. The story follows a young girl named Ginny, a bright and somewhat nerdy girl who feels out of place among the school elite. When several students begin to mysteriously disappear, Ginny and her group of friends decide to investigate the strange situation.
As they explore the school hallways, they realize that a biology-obsessed teacher is behind it all, attempting to create an army of "superior" young people to compete in a major academic tournament. While Ginny and her friends try to unravel the horrible secret, they face hilarious and terrifying situations, filled with unexpected twists. As more friends turn into zombies, the situation becomes increasingly chaotic.
With the help of a rebellious former student who has witnessed the professor's experiments, Ginny must race against time, confront her fears, and save her friends before they fully become brainless creatures. In a climax filled with action and laughter, the high school students will not only fight to survive but will also learn what it truly means to be a "zombie" in a world where popularity and social pressure can be more deadly than the creatures themselves.
