While at each location, Fieri talks to the staff as well as the customers to get their thoughts on the food. Many episodes feature eateries that are connected by a common thread, such as burgers or comfort foods but its all here on Diners, Drive-Ins and Dives.

She can rely only on her estranged 17-year-old daughter, whom she remembers as a 9-year-old, and a handful of devoted friends, as she struggles to continue practicing medicine, despite having lost nearly a decade of knowledge and experience.

Told from multiple points of view, as a means to explore issues of perspective, bias, and trauma, this compelling drama is inspired by the disturbing stories surrounding a Midwestern couple who adopts a girl with a rare form of dwarfism.

As they defend their family from the daughter they've grown to believe is a threat, she fights her own battle to confront her past and what her future holds, in a showdown that ultimately plays out in the tabloids and the courtroom.
