7's Karen Hensel shows us, we're also hearing from a woman who was there and called loved ones as the building came down around her.

It was 1.22 a.m. Ring video from a hallway inside Champlain Tower South captured the thunderous roar as the building began to collapse.

That's what woke me up and threw me out of bed.

Reza Rodriguez was asleep in Unit 907.

And that's when I said to myself, what the hell's going on?

We don't have earthquakes in Miami.

She ran to her balcony door.

Once I opened the sliders, this white cloud just went.

She tried calling her longtime friends, Elaine Sabino and Dick Augustine, who lived in Unit 1210.

No one answered.

A call to her brother went to voicemail.

The recording captured 15 minutes of horror.

Now one year later, wearing the same clothes as that night, Reza sat down with us to explain her terrifying escape.

So once I opened the door to the stairwell, my brain couldn't compete with what I was seeing.

It's like, what's going on?

Where's the building?

The building is gone.

I heard from the pile.

Some ladies scream up to me, please help me.

Please don't leave me like this.

It was pitch dark.

I just couldn't see her at all.

I kept hearing people crying and moaning.

Reza kept banging on doors, first helping her neighbor Yadi and Yadi's 8-year-old son.

Ada's waiting for us on the eighth floor.

I said, whoever we need to help, we help right on the way out.

They together rescued 88-year-old Ada and made it down seven flights to the garage.

I heard water running.

So I'm thinking water, electricity, we're not going to make it through there.

Firefighters rescued all of them from a second floor balcony.

A lot of people don't understand what we went through that night.

This is now sacred ground where 98 people died.

Once dubbed the mayor of Champlain Tower South, Reza Rodriguez holds on to the memories here of her neighbors and friends.

It just breaks my heart that all these people are just gone.

Even though Reza lost her unit, she still has to pay the monthly mortgage, forcing the 60-year-old to move back in with her parents.

Returning to the collapse site is hard.

I get physically sick.

I could just see certain people just sitting where everybody would sit.

And then I looked and I just, everything's gone.

Her friends she tried to call that night did not survive.

Richard Augustine and Elaine, they were my friends for 18 years.

You know, sometimes I look up at the sky and I talk to Dick and I talk to Elaine, and I'm sorry.

I'm sorry I couldn't help.

Reza Rodriguez called Champlain Tower South home for 18 years.

She tells Karen she thinks about that night and her friends every day since the collapse.
