The finch's is a very known family with two kids Jem and Scout and father Atticus
The kids are very curious an like to explore an play.
The Finch kids never knew who Boo Radley was, but they heard a lot of things including that he is a horrible person. A lot of time went by and they sti didnt know who he was. One night Jem and Scout was attacked in the woods and a stranger saved Jem and it turned out it was Boo Radley. They kids relized that he wasn't a bad person at all, just misunderstood.
As the walk home from school they find that someone keeps putting things in the Radley tree
The kids have never seen Boo because they say say he is very evil and should've been put in a asylum.
Boo saves Jem and, an him and scout relize that he is not a bad person at all.
