The life of Alan who turns from a convict to a master detective

It is not a logline. We need to know a reason why Alan wants to turn from a convict to a master detective. This can be done by having the inciting incident at the start of the logline. This would in turn clarify the goal. It is not good to start with “The life of Alan…” as the film would not contain the entire life of Alan, just some of the most important moments in Alan’s life in terms of telling the story. The use of the characters name is not as important as their function (in this case convict). With the function you can also add the flaw of the character as their is currently no flaw. The other section “…who turns from a convict to a master detective” is quite generic and too vague. Setting up the inciting incident at the start of the logline would also help here as it would make Alan’s reasons (goal) for turning into a master detective more specific. It is not clear whether he has to become a master detective because of a circumstance or if he is doing it by his own choice. Does someone (i.e. antagonist) try to stop him? You can also add the stakes for the character in the logline but that could make it too long as you should try to keep the logline within 25 words.
