The Symbol of the Unconquered (also known as The Wilderness Trail) is a 1920 silent "race film" drama produced, written and directed by Oscar Micheaux.
When Driscoll and friends enlist the KKK to run Van Allen off his oil-rich land, Eve saves the day by riding into town for help.
Two years later, Van Allen is a successful oil king; Eve delivers a letter revealing her black ancestry, and the two are able to declare their love for each other at last.
Though Abe is a comical and harmless figure, his facial grimaces (from being cold and wet) scare an already exhausted Eve who runs off into the woods as Driscoll laughs uproariously at her distress.
At the post office Driscoll picks up a letter meant for Van Allen that was accidentally dropped by the mail man.
They enlist the help of Bill Stanton, a Ku Klux Klan member, and continually leave threatening notes outside of Van Allen's tent in order to get him to sell.
Their attack fails thanks to some help from other members of the community, specifically a colored man with a brick, and afterwards Van Allen finally learns that the reason his land is so sought after is because of the abundance of oil fields.
