00:00:00.000 --> 00:00:02.000
Hook. A commuter steps onto an upward escalator, but the single step beneath them moves downward while every other step continues upward.

2
00:00:02.000 --> 00:00:05.000
The commuter tries walking faster. The isolated step matches the effort exactly, keeping them perfectly still as people glide past.

3
00:00:05.000 --> 00:00:08.000
A stranger offers a hand, but the escalator creates a second backward-moving step beneath the stranger. Both are now trapped, walking in place.

00:00:08.000 --> 00:00:10.000
An elderly pedestrian calmly uses the stairs, reaches the top first, turns back, and gives them a disappointed thumbs-down.
