The synopsis reads:

Lost in a mysterious cloudbank, a rookie pilot and her four teenage friends must contend with a freak mechanical failure that first sends their small plane climbing to an impossible height, and then plummeting through endless mist.

After regaining control, the survivors are confronted with a horrifying realization – the very ground beneath them has vanished and a malevolent force lurking in the clouds wants them dead.

A promo trailer for the film was revealed at last year’s American Film Market.
