A man and a woman are looking for each other. Sometimes they feel that they are going to see each other, but it is just an illusion of the mind. The gazes out of the frames lead to somewhere invisible. The repetition of images recalls the feelings of a loosened memory.

In the depths of the underground coal mines, where danger awaits and darkness prevails, Nam and Viêt, both young miners, cherish fleeting moments, knowing that one of them will soon leave for a new life across the sea.

In mining, a slag heap refers to an artificially raised hill consisting of the cleared waste that accumulates during the extraction of raw materials. Birch trees now grow where workers from near and far once went underground to labour hard for very little money. Nowadays, this is a place where men meet to have anonymous sex and share moments of intimacy. “I think he was gay too,” says one of these men about his father who was a miner. Today, as in the past, those who cannot find shelter elsewhere live here. Home is far away, returning is impossible. Human beings need more than water and a tent.
