Marcy is a distracted, anxious, and unethical young adult who can barely focus on her dog walking job. Her personal life is challenged by caring for her mentally-ill brother and her non-coping mother. When she loses her client's corgi, Sam, the attention sets off a dog search that explodes on social media and becomes a national obsession, inspiring Sam's owner to fantasize about fame and fortune while emphasizing Marcy's guilt.
