Billy McMahon and Nick Campbell are two middle-aged watch salesmen who find themselves made redundant when the company they work for goes out of business, due to the digital age rendering their sales skills obsolete. Searching for employment, they stumble upon competitive internships at Google, despite their lack of technical expertise and familiarity with contemporary digital technology. In a bold move fueled by desperation and a can-do attitude, they manage to bluff their way through an unconventional interview, leveraging their experienced salesmanship to secure places in Google's summer internship program.

Upon arrival at Google's campus, they are teamed up with a group of bright but socially awkward interns for a summer of challenges, with the promise of full-time employment for the winning team. The interns are instantly outmatched by their younger, more tech-savvy competitors. The pair faces an uphill battle adapting to the company's progressive culture and rigorous demands. Being significantly older than their peers, they initially struggle to fit in and are frequently the butt of age-related jokes. However, their unique life experiences, unorthodox approach, and willingness to break out of their comfort zone soon help them make valuable contributions to their team's progress.
