EMBEDDED WITH SURVIVORS OF THE PARKLAND, FLA. SCHOOL SHOOTING, CBS NEWS BRINGS VIEWERS INSIDE A MOVEMENT AS STUDENTS TURN GRIEF INTO ACTION IN "39 DAYS"

Saturday, March 24 (8:00 PM, ET/PT)

CBS News journalists, embedded with survivors of the Parkland, Fla. school shooting, take viewers inside the creation of a movement as students turn grief into action, in 39 DAYS, a one-hour documentary to be broadcast Saturday, March 24 (8:00 PM, ET/PT) on the CBS Television Network.

In the days after a former student at Marjory Stoneman Douglas High School shot and killed 17 people, CBS News began following a group of students who banded together to fight back. They set out to let the world know immediate change is needed to save lives. The documentary captures students' raw emotions as they grieve and work around the clock in an effort to change the gun laws of this country.

"We're trying to get people to stop dying," says student Emma Gonz�lez.

Journalists were also embedded with Andrew Pollack, whose daughter, Meadow, was killed in the shooting. Pollack's searing and powerful speech at the White House has made him one of the most visible of the victims' parents.

"It should've been one school shooting and we should have fixed it," Pollack told President Donald Trump that day. "And I'm pissed, because my daughter, I'm not going to see again."

Pollack says the focus should be on tightening school safety, not changing gun laws.

"It's great that the kids are out there together and that they have a voice," Pollack says. "I would tell them to focus their energy on something that's achievable that we could accomplish right now. What we need right now in this country is school safety."

His mission, he says, is to make schools as secure as courthouses and airports.

"Her presence is keeping me strong," says Pollack of his daughter, "to fight this cause, to keep the schools - we just gotta make 'em safe. That's all I want."

39 DAYS also includes strong voices from the Second Amendment conversation. The documentary presents a taut timeline of the tumultuous events from the first day of the shooting to the "March for Our Lives," which will take place in Washington, D.C. and cities around the country. The documentary will also feature reports from on the ground at the marches.

"Seventeen people. My peers, my teachers, they died," says student activist Delaney Tarr. "Ultimately, the only way I feel I can really heal is if I try to make a difference."

39 DAYS is produced by the team at 48 HOURS and CBS THIS MORNING.

Additionally, CBS News will provide extensive multiplatform coverage of the "March for Our Lives" beginning with CBS THIS MORNING: SATURDAY and continuing on CBSN, CBS News' digital streaming news network; on the CBS WEEKEND NEWS; online at CBSNews.com; and on CBS News Radio. Also, CBS SUNDAY MORNING and FACE THE NATION will have reports on Sunday, March 25.
