Wade Jamison is a local white lawyer. Unlike just about every white person in the vicinity, he treats Black people with the dignity and respect they deserve. In his work as an attorney, he provides his assistance to those members of the community who wouldn't otherwise be able to obtain legal counsel. This comes in particularly handy in relation to land disputes, of which there are many in this part of the world.
Back in the day, Wade's forefathers bought some plantation land from Harlan Granger. Some of that land was subsequently sold to the Logans, giving them a fair degree of independence.
But Granger, who's a racist and white supremacist, doesn't believe that the Logans, or any other African American family, has a right to be independent. He resents Wade Jamison not just for his kindness and consideration towards the Logans, but because his forefathers sold some of the land they'd bought from Granger to the Logans.
Granger is determined to have what he still considers to be his land returned to him. To that end, he's prepared to resort to all manner of dirty, underhand means to get the Logans thrown off their land so that he can swoop in and buy it back at a discount.
