On the train back to your parents' in another city, at one of the stations, you noticed four tall figures out of the corner of your eye. They were all well-muscled, so you immediately noted that they were military personnel, but from a different train.
Today was a cold day that seemed easy to survive on the train, but who knew that this 'easy' would not last long. You were riding in the lower berth right next to the toilet in the very last car of the train. The train stopped, heralding a short stop. The conductor of your car, as always, opened the door and a cool air blew into the car, but then... You heard the conductor's shout and a gunshot - a chill immediately ran down your spine and you jumped from your seat and ran to another car, ignoring the panic of others, the instinct for self-preservation. You ran past the second car, and behind you, screams, a shot, a scream, and so on, it seemed endless. Running along the third car, you glanced at the schedule, the next station was in 10 minutes. And the train had only 20 cars, not including the driver. You ran, feeling your lungs clogged with lack of air, but stopping meant falling with the others. You ran through the 4th...5th car, your heavy breath and a gunshot, a breath - a gunshot. Your ears were ringing, your eyes were darkening, you glanced at the board: car 9, arriving at the station in 8 minutes. You ran without stopping, realizing that time was running out, and the terrorists were getting closer and closer. You rushed past passengers, they looked at you in confusion, car 11, 6 minutes until arrival. You picked up the pace, feeling your chest pounding, 12...13, only the boards with cars 14...15 flashed before your eyes, only 5 cars left to run, 4 minutes until arrival. 16.. You yourself didn't understand how you ended up in car 20 and how you closed the door behind you, leaving the terrorists in car 19. The train stopped, the gunfire continued. The people in car 20 had long since realized everything. As soon as the conductor opened the door, everyone ran for the exit. Anyone who ran out found themselves instantly shot through the windows of car 19. You realized that if you exited, you'd end up in the same place as them, so with some effort, you opened the opposite door and slipped out, pressing yourself against the wall of the car. One of the mothers with two children followed you, realizing it would be safer to follow you than the others. You slipped past the windows and exited onto Piron, immediately running into the underpass, looking back to make sure the woman with two children was keeping up. As soon as you and she ran into the underpass that led to the station, you pressed the red button, locking the underpass door. You descended, avoiding the open area where you could be seen. You looked around, and crowds of people stared at you in confusion. Shots were heard outside, approaching the entrance, your lungs burning from the recent marathon. Your gaze caught four figures, the same ones you'd seen at the other station, and without thinking, you ran toward them.

• "Listen, we need your help. I know you're military or something like that, out there... You can hear it yourself. These aren't just people with guns. They're professionals."
