The camera crew arrived at 5:10 a.m., before the biscuits, and by 5:40 Deshawn Petty had been interviewed twice, filmed flipping 60 patties, and told by a producer that his spatula grip “reads as destiny.”

Petty, 22, has worked the grill at a Five Guys in Tallahassee for three years. As of this week, he is a lead in a five-part documentary series on Prime Video called “On The Line: The World Burger Games,” which follows crew members from local qualifiers in North America, Europe, and Australia to a global hands-on burger-building championship. The series was produced by Full Day Productions, the outfit that made the O.J. documentary, a résumé line Petty said he “had to look up, and then he cried a little.”

By 7 a.m., the crew had shot the fryer, the register, and Petty’s car in the parking lot, which the producer described as “the origin.” By 8 a.m., Petty had met the medical tent.

The medical tent is at every regional qualifier. It is staffed. It has ice. It has been used for grease burns, for a sprained wrist sustained during a spatula-spin warmup, and, in one early heat, for a contestant who fainted at the sight of 400 buns arranged in a grid.

“The stakes have never been higher for a #2 with extra bacon,” said the head judge, a franchise owner from Ghent, Belgium, who has judged 14,000 burgers and who grades on a card with four categories: structure, toast, ratio, and “the moment.”

Petty’s qualifier run was, by the footage, excellent. He built a double patty with grilled onions at 11 seconds, a time that made the camera operator say “oh!” on tape. He lost in the regional final to a 19-year-old from Lyon who toasts the bun with a blowtorch, a technique the judges scored as “confident” and Petty’s mother, watching from the third row, scored as “a lawsuit.”

The contract, which Petty signed on a clipboard in the walk-in, runs to 14 pages. Page 9 states, in plain language, that “the bun is final.” Petty said he read page 9 “four times, and then I signed it, because the camera was already on me.”

By 11 a.m. the crew had wrapped the shift. Petty was offered a standing interview for the series finale. He asked for it at 2 p.m., “after the lunch rush,” and the producer said the lunch rush “is the show.”

The series is streaming now. Petty’s mother, Denise Petty, has watched it twice. She said the family is proud, and she said the blowtorch kid from Lyon “is going to get somebody hurt,” and she said she has “told the producers this, in writing, on the back of a fry bag.”
