 Storekeeper Paul Manning (George Nader) is attempting to sabotage the completion of a telegraph line so he can have time to dispose of his stock before the near-by Army post is abandoned. He uses outlaw leader Roberts (Hugh Beaumont) and his gang in this effort. Troubleshooter Tim Holt (Tim Holt) and his pal Chito Rafferty (Richard Martin) investigate, but quickly get onto the wrong side of Terry Muldoon (Gail Davis), daughter of the telegraph line contractor.
