Broadcast #4 is the 4th video in the Clear Lakes 44 series.
The video has similar recording issues as the previous entries.
The video shows a man walk back and forth in an alley of some kind, and just wanders about. After a few minutes, another man walks up with a trolley and takes two of the boxes from the first man who helps him load them up. The two appear to talk, shake hands, and then go their separate ways, with the first man heading down the alley in the direction of the camera, and the second man taking the trolley and boxes, and going the opposite direction.
It is not stated what is in the boxes.
