When a deadly airborne virus threatens to wipe out the northeastern United States, teacher Elliot Moore and his wife Alma flee from contaminated cities into the countryside in a fight to discover the truth. Is it terrorism, the accidental release of some toxic military bio weapon -- or something even more sinister?
Unfortunately the movie The Happening is not yet available on HBO Max.
