He's All That reimagines the original plot of the 1999 teen classic She's All That.
The contemporary story follows influencer Padgett Sawyer (Addison Rae), who turns a guy at her school into a popular guy who can get any girl he wants. Unfortunately, she was hoping to have him all to herself. When she decides to find another guy to turn into prom king, her best friends Alden (Madison Pettis) and Quinn (Myra Molloy) say they're going to pick the guy for her, so it's more of a challenge.
They choose Cameron Kweller (Tanner Buchanan), a long-haired student who when he's not keeping to himself, is completely antisocial. Padgett goes to great lengths to get his attention, then tries to work her magic on him.
