There are two people (men (though one of them maybe woman)) in this music video. They ride in the train compartment. There is subdued lighting in the train compartment. And it looks like sepia filter was applied. In this compartment they do many differemt things: playing chess, read newspapers, talking and fighting.
In the end of the music video train moves into tunnel, camera zoom out from train and we realising that all happened in the snow globe.
