In it, two children frantically search for each other in spooky abandoned train depot.

As is tradition, the youngsters each wear one of Sia's signature two-toned black and white wigs.

But in an extra unsettling twist, nether of the faces are visible; instead their entire heads beneath the wigs are covered in black masks, giving the impression they have no faces at all.

After finding each other, they hold hands and sprint through the deserted station together, without ever removing the masks.

The song is from the soundtrack to Lion, starring Nicole Kidman and Dev Patel; with the theme of the video mirroring the plot of the film.

Based on the non-fiction book The Long Way Home, it tells the story of a man who searches for his family using Google Earth, having been separated from them at five years old.

Although fans can't tell for certain, neither actor seems to be Sia's talisman Maddie Ziegler, as they appear to younger than the now 14-year-old.
