The Stranger Things season 5 trailer, which you can watch below, teases all manner of interdimensional havoc and military firefights. It's soundtracked, fittingly, to a retooled version of Deep Purple 's "Child in Time," which originally appeared on the band's fourth album, 1970's Deep Purple in Rock.

The beginning of the end for Stranger Things draws near as Netflix unleashes the first teaser for its hit franchise’s return.

But there’s still hope among the spreading darkness in this trailer, because Stranger Things 5 still has a plucky band of brave friends willing to fight.
