Queen of the South season 5 will continue to follow Teresa Mendoza (Alice Braga), trying to climb up to the top and become the successful dealer in the world. She has encountered many hardships along the way, and her story is seemingly coming to an end in the upcoming fifth installment.

Queen of the South season 5 picks up where season 4 left off, with Teresa planning to expand her drug empire across the United States. To do this, she teamed up with Russian dealer Oksana Volkova (Vera Cherny), who could be the key to help her carter get to the top.

Teresa and Oksana made a deal, with the latter using her connection with the Russian mob in New York to help the former sell her products. If their plan becomes successful, Mendoza's character will be recognized internationally as a queenpin.

This could be a proper ending for Teresa, which means that Queen of the South season 5 might serve as the final installment. This speculation first emerged after Peter Gadiot (who plays James Valdez) seemingly hinted that the series is coming to an end.

In one of his recent Instagram posts, Gadiot shared a photo of himself getting ready to shoot new episodes of the crime-drama. The actor uploaded a selfie of him in character as James and wrote in the caption: "The neck tat is back."

What made the post intriguing is that he used the hashtag "#onlasttime." Fans were quick to speculate that Gadiot is hinting that the fifth installment will serve as the final run for the series. Some came up with certain theories and shared their thoughts about these.

Fans on Reddit suspected whether the post means the end of the series or the death of James. One user wondered what does Gadiot mean by one last time, while another one said it would be pointless to bring the character back only to be killed off eventually.

Right now, there is no official announcement from USA Network that Queen of the South season 5 is going to be the last. The cast and crew are currently filming new episodes, so there are a lot of works that needed to be done. The decision might be made later on or before the series returns.

Queen of the South season 5 is slated to come out sometime in 2021.
