When Addison Gerhardt's best friend, Devin Velma, begs for his help, Addi knows he's in trouble. After all, Devin wants to hit it big on the internet by pulling a stunt at an NBA game - one the entire nation will be watching. Addison can't turn Devin down, but he can barely manage talking to his teachers without freezing up. How's he supposed to handle the possibility of being a viral sensation? Addi's not sure why Devin is bent on pulling off this almost-impossible feat. Maybe it has something to do with Devin's dad's hospital bills. Maybe it all goes back to the Double-Barreled Monkey Bar Backflip of Doom. Or maybe it's something else entirely. No matter what, though, it's risky for both of them, and when the big day finally comes, Devin's plan threatens more than just their friendship.
