HBO's music drama "Treme" is ending its run after four seasons. The cable network has announced the fourth season renewal on Saturday, September 22, adding the final chapters are approaching with shorter season.

"We are going to be back for a season 3.5," co-creator David Simon said at the screening of third season opener. "HBO, upon viewing the 10 (season-three episodes) that we gave them and what we've done, they want to see the end of the story. They fought very hard to give us half a loaf. We're going to take it and run."

The drama has been struggling in ratings despite critical acclaims. It becomes HBO's lowest-rated drama for pulling fewer than 500,000 viewers in the original airings. Simon and co-creator and Eric Overmyer previously also said that the series would end in fourth season.

Series star Khandi Alexander spoke further about the end of the series, telling THR last week, "David [Simon] has made it clear that he wants a conclusion, and it is my understanding that, as of today, we're very close to being able to have a conclusion - and I'm looking forward to that. I think often times it's the audience that suffers when a show isn't given the opportunity to have a beginning, middle and end."

"Treme" returns for third season on Sunday at 9 P.M. It is yet clear how many episodes the fourth one would have.
