Aaron Carter was rather popular when he was young. He had a hit single, girls really liked him and his older brother was in one of those boy bands. It looked like his career would never stop. Until it stopped because people realized he wasn't that good. As he grew older the cute kid demographic moved on and so did his career. So the next step was obvious, turn him into a teen heartthrob via movies.
Not a great plan as this is the only movie he ever headlined. It's about a popstar which you should have gotten from the title. He's going to go on tour this summer but he's failing math and his mother won't let him. In the real world I don't see this happening but they have to get him back to school somehow and so he must do better in math or else there's no summer tour for him.
Of course nobody knows who he is because he's wearing glasses. If it works for Clark Kent it's definitely going to work for him right? I mean it's not like he's the biggest popstar on the face of the planet and girls all over the place have his poster in their rooms or anything. Nah, glasses are fine.
Well high school shenanigans ensue. He winds up with a cute girl who's also his math tutor, she finds out who he really is, they fall in love, he passes math and the summer tour is a go. End credits.
Sure there's more that goes on but honestly who cares? Aaron Carter can't act and as far as I'm concerned can't sing either. There is literally no reason to see this other than if you're a masochist and love to watch bad movies.
