For a three-act plot analysis, put on your screenwriter’s hat. Moviemakers know the formula well: at the end of Act One, the main character is drawn in completely to a conflict. During Act Two, she is farthest away from her goals. At the end of Act Three, the story is resolved.
Act I
Franklin grows up, becomes a Philadelphia printer, and gets involved with politics. He's trying to make his state a better place by developing things like schools and a military when the French and Indian War breaks out.
Act II
Franklin does his best to help craft a proper army for the colonists. He gets in debt for one general, and then gets involved in an argument between the colonists' Assembly and the governor about how to spend their money on defense.
Act III
Franklin goes to England to argue for the colonists in their dispute and manages to resolve the issue, then returns to America and finds that the dispute has been resolved in a different way.
