The stairs were concrete for the wide shot and rubber for everything else, and knowing which was which was most of the job.

Vera Nunes climbed them twice before the crew came in. Twenty-two treads, a half landing at eleven, a turn, then eleven more down into the lobby of a bank that had not been a bank since 1961 and was now the ground floor of a stage outside Budapest. She went up counting with her hand on the rail. She came down without counting.

Two and a half seconds if she let it go. Three and a little if she fought it. The shot wanted the second one, a woman trying not to fall and failing at it, which has a different shape than falling. Nobody in an audience could name the difference. Everybody could see it.

Ray Meeks came in at seven with two coffees and handed her the sweet one, which she did not drink, which he knew.

"They moved it into the flashback," he said.

"I heard."

"Then you heard the rest of it."

"I heard they hired a girl."

"She's twenty-three." He said it like an apology. Ray had been coordinating as long as Vera had been falling.

Adela Roth was fifty-one and playing herself at twenty-four for eleven minutes of the picture. The technology for the face had gotten cheap. The technology for the body had not. Somebody still had to go down the stairs.

"Is she any good?" Vera said.

"She's fast. Wire work. Two features."

"That isn't what I asked."

"No," Ray said. "It isn't."

Kit Alvarado arrived in a puffer jacket with the sleeves shoved past the elbow and shook Vera's hand like she was being graded on it. She had the forearms. That much was true.

"I've seen everything you did on the Hollis pictures," she said.

"No, you haven't," Vera said. "You've seen Adela do them."

Kit laughed. Then she understood it was not a joke and stopped, and Vera liked her a little for how fast the laugh went away.

They put the pads down and walked it. Vera took her through the count. First hit on the fourth tread, hip and lat, never the elbow. Second on the seventh, rolling onto the outside of the shoulder. Then the landing at eleven, where the whole thing had to look like an accident and be a decision. There were sixteen inches of usable pad on that landing. The frame line ran two feet past it, so every inch of padding the eye could not see was every inch there was.

"Where does it hurt tomorrow?" Kit asked.

"Left ribs. Both knees. Somewhere in your neck you can't point at."

"That's all?"

"That's the good version."

They ran it at half speed. Kit's hand came up.

Vera saw it before the wrist did, the arm swinging out at the fourth tread, the palm turning toward the world. It is the oldest reflex there is and it is worth about eleven thousand dollars in a hand surgeon's office.

"Again," Vera said.

The hand came up again.

"You're posting."

"I know."

"Knowing isn't the part."

They ran it eleven times before lunch. Nine times the hand came up. Twice it stayed down, and both of those times Kit landed a foot and a half short of the mark, because a body that has stopped protecting itself has to be doing something else instead, and nobody had taught her what.

The release came on a Thursday, carried in by a polite young man from post named Owen who had two pens and offered her both.

They wanted a volume scan. Sixty-two cameras in a ring, four hours, her body at rest and in motion, and then the fall itself captured as geometry instead of as footage, so the face could be laid on later, and so, in a paragraph on the second page set in the same type as everything around it, the captured performance data could be used in this and any related production, in any medium now known or hereafter devised, in perpetuity.

"It's standard," Owen said.

"I know what it is."

"It's really only so we can put Kit's face on the plate. And Adela's on Kit's, technically. It's a whole chain." He was cheerful about the chain.

Vera had been doubling Adela Roth for nineteen years. She had been set on fire twice for her and hit by a car once. A stunt magazine had added up her falls for a profile that ran with a photograph of Adela, and made the total slightly more than the height of the Chrysler Building. She had never signed anything that outlasted the picture.

"What happens if I don't."

Owen looked genuinely sorry, which was worse. "Then we'd shoot it with Kit," he said. "Somehow."

She thought about the sixteen inches of pad, and the girl's hand coming up on the fourth tread, and the ten days the schedule had lost to weather in Prague.

She took the pen and did not use it. "Monday," she said.

They shot the stairs on a Friday, second unit, which meant no Adela, no director, no video village full of people in good coats. It meant Ray, a camera operator named Bence who had done four pictures with them, and a medic sitting on an apple box with his phone.

Kit went first. It was her gag on the call sheet, and Ray was not a man who took a thing away from someone before they had been given the chance to lose it.

Take one, the hand came up at the fourth tread. Nothing broke. She hit the mark and lay there breathing.

"Reset," Ray said.

Take two, she held the arm in. Vera watched her hold it. Watched the discipline of it eat the count. Watched her take the seventh tread on the elbow instead of the shoulder and arrive eight inches long, past the pad, onto the deck. The sound was not loud. The bad ones never are.

The medic put down his phone.

Kit sat up before anyone reached her, which is the first thing you learn and the last thing you forget, and held her left wrist against her stomach like a bird she had found in a road.

"I'm fine. I can go again."

"You can," Ray said. "You're not going to."

Nobody said anything to Vera. Ray looked at her and she was already stripping the tape off her wrists to put fresh on.

She went at 4:40 with twelve minutes of usable light. She did not think about the stairs. She thought about the rail at the turn, which had one screw head standing proud by a sixteenth of an inch, and which she had marked in her mind on the first morning without deciding to.

Fourth tread, hip and lat. Seventh, the outside of the shoulder. The turn. Her left hand stayed flat at her sternum, where it had lived since 2009, when a coordinator in Malta made her run a flight of stairs forty times holding a roll of gaffer tape to her chest and told her the tape was her hand and the hand was her career.

She landed on the mark, both feet inside the sixteen inches. Three point one seconds, and the last half of it looked like a woman losing an argument with a floor.

"Check the gate," Ray said. "We're clear."

Bence gave her a thumb from behind the camera. The medic went back to his phone. Kit stood at the edge of the pad with her wrist wrapped, not clapping, because you don't, but she had both eyes open and had not blinked once the whole way down.

"How do you not put your hand out," Kit said.

"You do," Vera said. "You put it somewhere else."

The plate came back from post eleven weeks later. Vera watched it in a screening room in Burbank with nine other people, none of whom knew she was in the room, one of whom waved at her because he thought she was somebody's assistant.

On the screen a young woman went down a flight of stairs in a bank in 1998. It was Adela Roth's face at twenty-four and it was not Adela Roth, and the face did what the face was hired to do, which was to be frightened and beautiful inside the same eleven frames. Under it, at the turn, in profile, was Kit's jaw.

Under that was Vera.

Nobody in the room could find her. Her name would sit on the sixth of eight cards in a crawl the platforms would compress to the width of a thumbnail. Her body was on a drive in a building in Culver City, in perpetuity, in any medium now known or hereafter devised.

At the fourth tread the left hand stayed at the sternum.

There it was. A hand that did not come up when everything built into a primate says it must, on one woman's body, wearing a second woman's face, wearing a third woman's jaw. Nobody in that room would ever see it. Nobody in any theater would. It was the thing she had spent nineteen years making, and it was hers, and it was on the screen, and it was perfect.

She sat through the second pass. Then she went out the fire door into the lot and called Kit, who had a brace on her wrist and a call time in Atlanta in the morning, and told her about the tape.
