In flashback, the Maverick brothers explain to Dandy Jim Buckley (Efrem Zimbalist Jr.) why it wouldn't be healthy for them to set foot in Texas. It seems that, back during the Civil War, both Bret (James Garner) and Bart (Jack Kelly) had signed on as trail bosses for a cattle drive. After meeting resistance from female rancher Laura Miller (Aline Towne), our heroes are forced to shoot one of Laura's hired guns--and soon they're on the lam from the law, charged with murder. The Mavericks' search for a mysterious "tall man" who may have witnessed the shooting is a fascinating precursor to Richard Kimble's pursuit of the elusive "One-Armed Man" on the later TV series The Fugitive--which, like Maverick, was produced by Roy Huggins. ~ Hal Erickson, Rovi
