The trailer for "The Price Of Glee" is out, and it shows Naya Rivera's father reflecting on the impact of the show on his daughter's life.

The new documentary series from Investigation Discovery shines the spotlight on the legacy of the show and the deaths of three of the show's cast members — Cory Monteith, Mark Salling and Naya.

The trailer, which was uploaded on YouTube Thursday, opens with a female voice saying, "Glee was a phenomenon. The audience couldn't get enough of it."

"It took all these people, and it turned them into stars," a male voice can then be heard saying.

"In May 2009, 10 young actors made their TV debut on Glee. By 2020, all of them would be famous. And three of them would be dead," a text on the screen reads.

Monteith, who played quarterback Finn Hudson in the popular show, died of an accidental heroin overdose in 2013 when he was 31. Salling, who portrayed Noah "Puck" Puckerman, died by suicide at age 35, just weeks before he was scheduled to be sentenced for possession of child pornography. As for Naya, she fatally drowned during a boat trip at a Southern California lake with her son Josey Hollis Dorsey in 2020.

The Ryan Murphy-helmed series ran for six seasons from 2009 to 2015 and also launched the careers of Lea Michele, Amber Riley, Chris Colfer, Darren Criss, Harry Shum, Jr. and Dianna Agron.

"We had a lot of tragedies..and you find out that somebody is not necessarily who you thought you were," a man's voice says at some point in the trailer.

"The bigger the show went, the smaller their worlds become," another voice can be heard in the video.

The trailer also features an on-cam interview with Naya's father, George Rivera, who describes his daughter's joy in being a part of the show.

"I knew that was the top of the mountain for Naya," he says. "For your kid, it was just surreal."

The trailer also contains clips showing Salling's body in a post-mortem bag and a police officer explaining how Naya may have drowned.

"I don't want to say the C word — the 'curse' word — but that's where your mind goes," someone says in the trailer.

The three-part docuseries will premiere on Investigation Discovery on Jan. 16 and will be available for streaming on Discovery+ on the same date.
