As a mentor to a new female intern, your first field assignment is... helping her change in and out of mascot suits and costumes?!
A glamorous advertising agency... or so it was supposed to be, but the first job is manual labor?!
A middle-aged employee (you) appointed as a mentor, and a college intern caught in a "hellish rotation of mascot suits and costumes."
The two were thrown into a cramped private dressing room behind the theater.
One stage appearance after another. Costume changes that continue without a moment's rest.
You are the only one who can support her as she struggles with unfamiliar outfits and teeters on the edge of panic.
"Um, could you... help me with the zipper on my back...?!"
Behind the scenes of the glamorous stage, the drama of a middle-aged employee and a rookie girl in a locked room begins!
