and she will need to be superhuman.

No woman has finished stage one,

and this course has been brutal tonight,

taking out some of the very best.

- There you go, Jessie. - Well, this woman's so skilled,

a pole-vaulter in college

but now trains relentlessly at obstacles.

- See how big that jump was there for Jessie Graff.

- Only a handful of women have ever gotten past

the Propeller Bar, so that's a big step,

and here comes another, the Giant Log Grip.

- This crowd is chanting like she's a rock star.

- But this obstacle has been lethal tonight.

- Come on, Jessie.

- Hold on. Hold on.

- Uh-huh, yes. - She gets through.

- That was, like, a stunt move there for Jessie Graff.

- Picture-perfect, now the Jumping Spider.

Jessie and Meagan Martin the only two women

ever to get past this obstacle.

Can she do it again here?

Yes. - Wow. Wow.

- Jessie Graff in the Jumping Spider.

- Boy, she got in there with authority.

- Well, she's a stuntwoman on "Supergirl,"

but she's the one who's flying tonight.

Speed is always a challenge on stage one.

Jessie got fatigued and ran out of gas last year,

but she has a great pace going.

- Come on, Jessie. Come on, Jessie.

- Jessie Graff on the Sonic Curve.

Beautiful technique onto the rope.

Perfect. But now the Warped Wall.

She couldn't get up it last year.

In fact, no woman has ever gotten past it on stage one.

- Well, Matt, can you feel it?

Can you feel history in the making here?

- Yes! - Oh, yes.

- Jessie Graff continues to deliver, the first woman

ever to get up the Warped Wall on stage one.

- Oh, my goodness.

Matt, it's about to go down.

It's about to go down.

- One obstacle left. - Oh, my goodness.

- So close to history.

- Got it. - Makes the first leap.

And she can feel it. - Oh, my goodness.

- This woman redefining strong.

- Put this on Instagram.

Put this on Twitter. The internet is about to blow up.

- She is smiling out here.

She knows.

Jessie Graff.

- Oh, my goodness.

- She's gonna make history.

- History. - The first woman

ever to complete stage one.

Jessie Graff has done it.

And this is one of the toughest stage one courses

we've ever had,

and she had over 12 seconds spare.

all: Jessie, Jessie, Jessie, Jessie, Jessie,

Jessie, Jessie, Jessie, Jessie.

- Well, that's got to be our POM Wonderful Crazy

Healthy Run of the Night.

With one hand, Jessie Graff reaches up

and makes history

as she gets over the Warped Wall,

and at that point, she knew she could finish.

Look at the smile on the Flying Squirrel.

And especially when she saw the buzzer.

She just did what no other woman has done.

- For the first time ever a woman

will be facing stage two at "American Ninja Warrior."
