To uncover these details, Sawyer interviewed members of Simmons' inner circle. This included Teresa Reveles, who served as the fitness icon's house manager for 35 years [6]. Reveles provided a rare perspective on the private life of the star.

"This is the first time I've spoken about it," Reveles said [6].

The documentary utilizes archival footage and new interviews to trace the trajectory of Simmons' fame. By speaking with the last person to see him alive, the special attempts to provide closure to the mystery of his absence [6].
