Scene: Inside an apartment building hallway.
(The scene opens with MARK and LENA in the hallway, looking concerned.)
MARK: Lena, do you smell that? It smells like smoke.
LENA: Oh no, you're right! It's coming from the third floor, I think. We need to **evacuate** immediately!
MARK: The fire alarm isn't going off. Maybe it's not a big fire?
LENA: Don't wait for the alarm! We have to get out now. Do you remember the **fire escape** plan?
MARK: Yes, go down the stairs and meet at the assembly point.
LENA: Exactly. We should go together. Take the stairs, never the elevator.
(They quickly walk down the stairs to the ground floor.)
LENA: Okay, we're outside. Now we need to **call for help**. Do you have your phone?
MARK: Yes. I'm calling 911 right now.
(Mark holds his phone to his ear. A dispatcher's voice is heard.)
DISPATCHER: 911 Emergency. What is your emergency?
MARK: Hello, there's a fire at 123 Pine Street, Apartment 3C. We saw smoke.
DISPATCHER: Okay, sir. We're sending the fire department right away. Is anyone still inside?
MARK: I'm not sure. We knocked on our neighbors' doors, but they didn't answer.
LENA: Wait, what about Mrs. Jones from apartment 3A? I saw her car was here.
MARK: I told them about the address. The fire department will check for everyone. Let’s go to our **assembly point**, which is across the street near the big oak tree.
LENA: Good idea. We need to stay calm and wait for the firefighters.
(They walk toward the street. The sound of sirens can be heard getting closer.)
