Four men held together by one nightshirt have swum a vast distance without food. Close to death, their faces skeletal, they arrive at a busy port in India. Local people lean over to drag them from the water. It looks like they are going to pull through. Now the sea morphs into a bustling road in the same city. The men are too slow, too exhausted to get up in time and a bus drives over the top of them, crushing them, ripping their bodies to shreds. Life is cheap here.
