Gearheads is a musical comedy in the style of Golden Age shows of the 1950’s and 60’s (e.g., Guys and Dolls, The Music Man, Hello Dolly). The action takes place over the course of one day in the present on a Saturday at an auto repair shop in Toledo, Ohio. Management is absent, so the mechanics turn their break room into an ersatz frat house, completely ignoring the one customer (Candy) who shows up. Later, wives/girlfriends surprise the men by bringing in lunch. Some rivalry between the sexes takes place until a shaky truce is reached.

Over the course of the day, we see young love (Gus & Julie), a troubled attempt at a relationship (Candy & Jeff), a happy couple who constantly kid each other (Jared & Karen), a cocky mechanic who gets under everyone’s skin (Zach), and a gruff father figure who tries to help Gus (Diesel). Jeff, Candy, and Gus embark on some theatrical emotional journeys, but it all ends happily as the final curtain comes down.
