This is a full version of this story.

It is Monday morning. Meena wakes up early after a Sunday vacation, due to her mother's nagging. Meena's mother gives her and Rahul food before they head to college. The sun is shining all around as they walk. Suddenly, Meena bumps into Rahul.

Mina - "Why are you always so careless?!!"
Rahul - "God gave you four eyes but you still bump into me."
Meena - "Don't insult me because I wear glasses, or I'll show you what I can do!!"
Rahul - "Come on, take my bag."
Meena - "Why should I...?"
Rahul - "Have you lost your memory? You lost the race yesterday, and as a punishment, you have to carry my bag for a week."

Meena's father is a police officer and was best friends with Rahul's father. After Rahul's father's death, Meena's dad promised to take care of Rahul. Since childhood, Rahul has lived in Meena's house, and they are good friends. But between friends, quarrels like this always happen.

Meena reluctantly takes the bag and heads to college. There, she meets Lalita, her best friend. Meena throws Rahul's bag and starts talking to Lalita.

Rahul - "Mina, who throws a bag like that?!"
Mina - "I can't take your bag; take it yourself!"
Lalita - "Let's hurry; our class is about to start."
Meena - "Yes, come on, let's go."

They meet Nil, Rahul's best friend, and talk about their annual function. Then, the professor comes in and starts teaching.

After a while, during a math class, the professor suddenly shouts.

Preeti (Professor) - "Rahul!! Did you hear what I said?"
Rahul - "Yes, mam…."
Rahul yawns and asks Meena, who is sitting next to him.
Rahul - "What did mam say?"
Meena - "She told you to wipe the blackboard with the duster."
Rahul goes and erases the blackboard. Everyone laughs at him. Preeti looks back, hearing the laughter, and says,

Preeti - "What did you do?!!! I asked you to write the answer to a question, and you wiped everything! Get out of my class right now!"
Rahul - "But mam, it was…."
Preeti - "I said right now!!!"
Rahul - "Okay, mam."
Rahul stands outside and says to himself, "My big mistake was asking her. I should have known she would do something like that." Then Rahul sees a jumping raccoon through the window. "What is the raccoon doing here, and why is it running so fast?"

On the other hand, Dev and Pallava, Meena's classmates, are trying to bunk college. They go to the field and see the security guard sleeping. It's the perfect time for them to escape, but they see a raccoon.

Dev - "Where did the raccoon come from?"
Pallava - "Let's take a look at it."

When Pallava touches the raccoon it bites him, and then it runs away from there and dies. Immediately, the security guard wakes up upon hearing Pallava's scream. Seeing them bunking college, the principal calls them to his office and scolds them for about five minutes. Suddenly, within a few moments, Pallava's nose starts bleeding. The principal says, "Pallava, your nose.... Are you okay?"
Pallava - "Principal, I feel weird."
Dev - "Principal, I guess after the raccoon bit him, his nose started bleeding."
Principal - "What? A raccoon?"
Dev - "Yes, there was a raccoon in the field, and it bit Pallava."
Principal - "Okay, now go to the nurse's room. You look very scary."

They go to the nurse's room.

Dev - "Nurse, Pallava's nose is bleeding."
Nurse - "Okay, wait, let me check."
After saying this, the nurse looks back and sees Pallava vomiting. It was not an ordinary vomit, but a vomit of blood. Seeing the blood, Dev and the nurse get scared.

Nurse: You are vomiting blood. Has anything like this happened before?
Pallava: No, never before.
Nurse: I don't have that injection. It's better to take you to the hospital. Lay down on the bed, you'll feel better.
Then she called the ambulance.

Pallava: I'm thirsty! I am thirsty!

Pallava kept repeating this for a long time and lay down on the bed.

Nurse: I have a medicine that will help you. Take these pills.

After saying that, the nurse is about to give Pallava the medicine when she notices that Pallava's eyes are completely red. The nurse cannot understand what happened.

Pallava: I'm thirsty! I am thirsty!
Nurse: Wait, I gave you water.

Suddenly, Pallava's hands and feet went numb. When the nurse gave him a glass of water, he said, "I want to drink blood. Where is blood? Nurse, I feel like you have very pure blood. I want to drink it!" The nurse became shocked.
Nurse: What are you saying? Do you want to drink blood...!?
Within a second, he jumped and bit the nurse's hand. The nurse started screaming.

After an hour, the ambulance arrived. The nurse informed them that he was bitten by a racoon and described the strange things Pallava had done. They took note of everything.

Then she went to her room with Dev, and similarly, the nurse's nose started bleeding. She also started vomiting blood, and her hands and feet were bruised. The nurse started chasing after Dev, but Dev began running.

Then the nurse bit everyone around her.

Dev somehow escaped and entered his classroom.

Preeti: Why are you yawning like this? What happened?
Dev: Mam... Zombie... Mam!
Preeti: Zombie? Tell me what happened. Sit here and explain everything.
Dev started telling them about the incident.

Urshita: What rubbish! I saw zombies in movies. How can zombies be here?
Dev: Believe me, I'm telling the truth! I think it all happened because of that raccoon. It started happening after the raccoon bit Pallava.
Tanisha: Zombie... We must escape now! If they bite us, we will become zombies. Hurry, Mam, hurry. We have to escape from here!
Preeti: Don't be in such a hurry. Keep calm. Dev, You might be mistaken somewhere. Zombies are not here...

Right away, Preeti goes to the door and sees many zombies trying to enter the room.

Suddenly, Basanti ma'am announced from the hall room,
"All the students are being informed that there is...
