Paramount Pictures marked the anniversary of the Terminator franchise's original fictional Judgement Day (August 29, 1997) with the release of a full-length trailer for its forthcoming film, Terminator: Dark Fate. It's technically the sixth film in the series, but it's actually been conceived as a direct sequel to the hugely successful first two films in the franchise: Terminator and Terminator 2: Judgement Day.
So Terminator: Dark Fate pretty much ignores all the other Terminator movies as existing in alternate timelines—an attempt to go back to the glory days of the franchise, complete with the return of Arnold Schwarzenegger, Edward Furlong, and Linda Hamilton, plus James Cameron on board as producer. Per the official synopsis, "27 years after the events of Terminator 2: Judgment Day, a new, modified liquid metal Terminator (Gabriel Luna) is sent from the future by Skynet in order to terminate Dani Ramos (Natalia Reyes), a hybrid cyborg human (Mackenzie Davis), and her friends. Sarah Connor comes to their aid, as well as the original Terminator, for a fight for the future."
The first teaser dropped in May, whereupon we learned that Dani has been on the run with her friends for a couple of years under the protection of soldier assassin Grace, the human/cyborg hybrid. And Luna's Rev-9 Terminator can actually split in two, the better to take out its target(s). An understandably suspicious Sarah nonetheless teams up with Grace to protect Dani and her friends, and we had a brief glimpse of Schwarzenegger's grizzled old Terminator, apparently hiding out in a remote cabin in the woods, ready to come to their aid as well.
