“When a teenager is accidentally transferred to a school for criminals, he will have to learn all the tricks of the trade and survive the competition in order to win the honor of being the city’s next don.”
I can see what the story is. But I have a question. Does he want to be the Don? Is it thrust upon him? What is the competition, it sounds like an event? I may approach it like this.
A teenager is wrongly transferred to a school for criminals. Desperate to just survive, he develops skills and a network that will see him become the next Don.
Is it a “normal” school that teaches its students to be criminals, or is the teen sent to a juvie hall, or whatever the correct term is? Either version is interesting in its own way.
