Synopsis by Hal Erickson
With Under Texas Skies, Republic's Three Mesquiteers underwent a slight change of personnel. Robert Livingston remained as Stony Brooke, but now Bob Steele was seen as Tucson Smith and Rufe Davis assumed the role of Lullaby Joslin. The story opens as Stony returns to his home town, only to discover that his sheriff father has been murdered by person or persons unknown. The new sheriff (Henry Brandon) resents the arrival of the Mesquiteers, going so far as to frame Tucson on a murder charge. It doesn't take long for Stony to figure out who was responsible for his dad's killing-and to bring real law 'n' order back to the community.
