The camera shows a wall on one of the underground subway platforms. With a weary motion, a middle-aged man is affixing a new movie poster to the large billboard. Right next to him, we notice an excited mouse watching him. The camera slowly focuses on the mouse. Then we see the dreamy look on the mouse's face. It watches the film poster, mesmerized. Then it looks up at the man and we see it panic. Now the camera shows the man’s face. At first, he does not understand, then his eyebrows furrow. He grabs the mop standing on the edge of the board with resentment.

At that moment, we turn back to Minco. The little mouse looks bewildered, sensing the approaching danger. Suddenly, it turns and starts to run. It dashes along the platform and enters the first hole it sees in the wall. We watch it run, swiftly moving through pipes and puddles. When it goes down another layer, it traverses a narrow, long corridor-like marketplace made up of opposing stalls. It's as if we can hear its rapid heartbeat. Other mice it encounters on the way look at it with laughter.

At one point in the corridor, it encounters another mouse. Leyla turns to it and says, "Hey Minco, what’s up?" but Minco keeps running without listening. Finally, at the end of the corridor, it sees a door and enters. Inside, we encounter an older mouse. Minco's mother exclaims, "Where have you been?" But Minco quickly enters another room, closes the door, and leans against it, breathing rapidly. We first see Minco's "teenage room," cobbled together from scavenged items, in a wide shot. Then we focus on Minco's face. After saying "Whew!" his breathing slows, and a sincere, dreamy smile appears on his face.
