Carl Casper (Jon Favreau), a skilled chef in a high-end Los Angeles restaurant, is bored by his job recreating the classics suggested by his controlling boss, restaurant owner Riva (Dustin Hoffman).

In a stinging review by a leading restaurant critic Ramsey Michel (Oliver Platt), Carl is called out for his lack of imagination. Introduced to Twitter by his tech-savvy son Percy (Emjay Anthony), Carl accidentally starts a flame war and loses his job.

Encouraged by his ex-wife Inez (Sofia Vergara) to start a Cuban food truck together with his son and his friend Martin (John Leguizamo), Carl takes to the road, hoping to reignite his creative genius.
