It's not really possible to pin down a single conflict in Harper Lee's novel, To Kill a Mockingbird. There are actually two major plots: Part One of the novel focuses on Jem's and Scout's fascination with their unseen neighbor, Boo Radley. The primary conflict in this section is the children's fear of Boo vs. their unquenchable urge to get a look at him. The children eventually come to realize that Boo is friendly enough, though the section ends with Boo still being invisible to them.
Part Two of the novel deals with the trial of Tom Robinson. There are many conflicts concerning the trial: Atticus' decision to defend a black man accused of raping a white woman is the major one. Whether Tom will receive a fair trial because he is black is another. The family's standing in the town is compromised because of Atticus' decision, and eventually, all of the Finches come to realize that Bob Ewell's threats following the trial may be for real.
The final conflict of the novel arises when the two plots are tied together in the end. When Bob Ewell, who had made the false charges against Tom, attacks Jem and Scout on a dark Halloween night, it is Boo who emerges to save them, killing Bob in the process. Though it is never discussed, Boo's decision to protect the children must have been a trying one; Sheriff Tate then has to resolve the conflict with a decision of his own.
