As the hugely popular Netflix series, “Orange Is the New Black” returns for its fourth season, Fox News Latino was on the ‘black carpet’ to talk with the actors about what surprises viewers may expect.

The show's writer and creator, Jenji Kohan (“Weeds”) is notoriously rabid about spoiler alerts, so none of the actors could say too much about the upcoming episodes, but what everyone was able to discuss was the depth of and assortment of characters on the show, as well as the dark turn the story takes in the new season.

Many of the actors hinted that the episodes will include topics taken from the headlines and that audiences will be shocked and saddened.

“It’s very dark. It’s very serious. It’s a hard ride. I think people are going to be like what is going on – for the first few episodes,” Abigail Savage, who plays Gina Murphy, told Fox News Latino.

The show is based on Piper Kerman’s memoir, “Orange Is the New Black: My Year in a Women’s Prison,” which describes her experiences at FCI Danbury, a minimum-security federal prison.

“Orange Is the New Black” streams on Netflix and first premiered in 2013. It is one of the streaming services most-watched originals, and it has received several Emmy and Golden Globe Award nominations – with Uzo Aduba taking home the 2015 Emmy for Outstanding Actress in a Drama Series.

The show revolves around Piper Chapman, played by actress Taylor Schilling, a woman in her 30s living in New York City who is sentenced to 15 months in Litchfield Penitentiary. Piper was convicted of transporting drugs for her international drug smuggler girlfriend, Alex Vaus, played by Laura Prepon.

Despite the soap opera-style plotlines, the strength of the show from its inception has been the diversity of its characters. White, black and Latino, old and young, gay, straight and transgender – along virtually every dividing line, OITNB, as it’s known to its fans, offers a number of complex perspectives that are deftly interwoven into riveting stories.

“We have one of the most diverse casts in all of TV. Different ages, sizes, colors, nationalities, religions, backgrounds. This show changes who you consider would be a lead. Who that looks like,” Jessica Pimentel, who plays Maria Ruiz, told FNL.

About the upcoming season, Pimentel warns: There will be heartbreak.

“There are several moments that are just so powerful, and I think the audience will feel it,” she said.
