When Henry Robinson's daughter Starr is born with Williams Syndrome, he swears to devote his life to making her happy. More than twenty years later, Henry works at Frankie's Funhouse, where he repairs the animatronic band that Starr loves, wrestling with her attempts at living outside the family home. His wife wishes he would allow Starr more independence and turn his attention a little more to their own relationship and their other daughter, Melanie. As tensions mount Henry's young coworker, Darren, reveals he needs to get to Chicago Comic Con to win back his ex-girlfriend, so Henry packs Starr (and her pet turtles) and Darren (still dressed as Frankie the mascot) into the van for a road trip no one was prepared for.
