Jason Gedrick and a small group of Marines are stranded in the remote Afghan desert. But it ain't the Taliban that's worrying them, it's these giant refugees from Tremors. In fact the big worms prove to be an ally of sorts by doing better against the Taliban than themselves but battling these enemies is something not covered in their training.
Unfortunately the movie Sand Serpents is not yet available on HBO Max.
