This year's fun fair will have a Pride Carnival theme and twelve-year-old Mac couldn't be more excited. Mac convinces his best friend, Amy, to do a Sonny and Cher drag number. He has their outfits all planned out, right down to the bellbottoms and fur vests. And he wants their performance to be perfect too so he pushes Amy to rehearse every day. Every step, every wave of the hand, every lyric has to be spot on. But Amy has had enough--the day before the event, she reveals that she never wanted to be Sonny. Why can't she be Cher? Mac refuses to even consider it. There can only be one diva! With no time to recast, Mac plans to go solo. But he's miserable without his best friend. Can the two of them patch things up in time?
