Henri “Halti” Haltiwanger’s mom says he’s “charming as a verb” — and she’s right! Henri’s parents are Haitian immigrants. While his dad is their building’s Super, his mom is studying to become a firefighter. He’s popular at his high school and runs a successful dog walking business. The thing is: he tells customers that there’s an entire network of dogwalkers, of which he’s just one. When his neighbor and fellow high schooler Corrine’s mother hires him to walk their dog, Corrine quickly uncovers his sham of a company.
