Spoiler warning: This story describes the ending of the "Tulsa King" Season 4 premiere.

The fourth season of "Tulsa King" opened on Paramount+ with a shock ending, Entertainment Weekly and TVLine reported. A private jet carrying Margaret Devereaux, played by Dana Delany, and Oklahoma Gov. Cal Thresher, played by Neal McDonough, goes down over the Pacific Ocean, the outlets reported. TVLine reported that the pilots are seen passed out in the cockpit before Dwight's sister, Joanne, wakes him with the news.

The episode starts well for Dwight Manfredi, played by Sylvester Stallone, TVLine reported. He launches a legitimate company, Friedman Enterprises, whose name is an anagram of "Manfredi," according to TVLine. EW reported that Dwight goes to New York for a national meeting of mob bosses, where Quiet Ray stays a threat.

Stallone, who also produces the show, said the twist was meant to stun viewers. “I wanted people’s jaws to drop,” he said in an interview with EW. He added that he wanted "the audience to get upset a little bit," EW reported. Stallone also teased the fifth season, which EW reported will move the show to New York.

Decider gave the season a "stream it" verdict. Its review credited the return of Terence Winter, who ran the first season and wrote the premiere, with a more emotionally grounded season. Decider named Thresher's lieutenant governor, Amanda Clark, played by Gretchen Mol, as one of the season's new threats.

TVLine left open whether the two characters are truly dead, while EW's interview discussed the decision to kill them off.

What we know: The Season 4 premiere ends with a plane carrying Margaret and Thresher going down over the Pacific, and Stallone says the shock was the point.
What we don't: How the loss will shape Dwight's story for the rest of the season.
