A seventeen-year-old high schooler named Hunter works as a cool hunter, finding and selling new trends to his corporate sponsors.

Together they are drawn into a mystery when one of Hunter's bosses disappears after she runs a 'cool tasting' for a new brand of shoe. What he finds ends up to be nothing like he had expected.
