In the series premiere, Craig Robinson, a musician looking to earn some extra cash, takes a job as the new substitute music teacher in efforts of winning the affections of a former high school girlfriend Victoria.
Craig invites rock legend Neville Rex (special guest star Gary Cole) to speak to his class in hopes of securing a recording contract deal for Nasty Delicious. Meanwhile, Victoria advises the teachers on a good investment, but their spending gets out of hand. Also, Principal Taylor's old groupie habits resurface.
Craig asks Jimmy to move in with the hope that he'll push the sloppy and jobless Ben to become a better roommate. Meanwhile, Ashleigh and Samir do some detective work to track down Supervisor Dalton's dog that Principal Taylor lost.
Craig organizes a night out with the teachers in hopes of getting some quality time with Victoria, but then a chance meeting with Victoria's friend takes him on a different course. Meanwhile, Jimmy suffers an existential crisis.
Craig hopes that a fund-raising auction will save his job and provide him with the perfect opportunity to make his move on Victoria, who is considering following her boyfriend to New York. Meanwhile, Samir tries to let Ashleigh know that he wants to be more than just friends.
In the Season 1 finale, Craig looks forward to a Nasty Delicious summer tour, but soon considers ditching those plans. When Earth, Wind & Fire show up and invite Craig along on a yearlong tour, he must decide whether to leave his brother, co-workers and students behind. Meanwhile, Samir feels guilty about seeing Ashleigh at her stripper job.
