The Dennis gang wants to rob the bank of the sleepy peaceful town of Plainview, Texas. Small town banks like this one have less money than large city banks but they're easy prey. Barlow, the gang's contact in town, assures them that Plainview only has an old marshal, Pete MacKay, who shouldn't pose any problem. The gang heads to Plainview. In town, storekeeper Jack Wright runs his store with wife Martha and brother-in-law Wally. Marshal MacKay and doctor Lacey are playing chess inside the store. Jack Wright makes his daily deposit at the bank and then returns to the store. The Dennis gang arrives and robs the bank, killing a teller and the alerted marshal. In the street, storekeeper Jack Wright picks the dead marshal's gun up and shoots fleeing robber Alvin Dennis, from a great distance. Townsman George Henderson finishes Alvin off with a shotgun. The bandit drops the loot and the bank recovers it. The townsfolk proclaim Jack Wright and George Henderson to be heroes.
