Fort Worth stars Randolph Scott as gunfighter-turned-newspaperman Ned Britt. Setting up shop in the eponymous Texas town, Britt tries to expose the crooked machinations of cattle baron Gabe Clevinger (Ray Teal). This brings him into conflict with his old friend Blair Lunsfold (David Brian), who has cast his lot with Clevinger. Further complicating matters is Lunsford's fiancee Flora Talbot (Phyllis Thaxter), who falls in love with Britt. As tensions threaten to erupt into all-out bloodshed--especially when Clevinger deploys brute force to prevent the arrival of the railroad--Ned Britt is forced to rethink his newfound philosophy that the pen is mightier than the sword.
