After his brother is gunned down and robbed, Tom Carter searches for his killer.
Jerry Carter is shot by an Outlaw who ambushes him in his way home, knowing that he was carrying a lot of money taken from the bank. Before dying, Jerry tries to write the killer's name in mud.
Tom Carter, his brother, finds his body, and vows to avenge him. He starts looking at Green Waters, a town dominated by Shannon, the rich landowner, and his enforcer Lee Rast, a gunslinger. Shannon is trying to buy even more lands from the poor.
Bill Joyce, who refuses to sell, takes a beating from several men, and his property license is robbed. He manages to recuperate it, but then Lee Rast shoots him in the street, and he almost dies.
Tom saves the life of Jack Buchanan, an old timer gold prospector, and then he starts being the victim of several attempts on his own life.
Ringo Brown appears in town unexpectedly, telling that he had killed Jerry, and offering money to anyone who tells him where to find Tom Carter.
Cora hurries on horseback to Jack's farm, where Tom is hiding, to inform him.
That night, Cora is assaulted in her room by Ringo Brown, but Tom clobbers him from behind, and drops him in Zelda's room.
Jack escapes another attempt on his life when he fakes giving away a purse containing a map of a gold mine; inside, there was a venomous snake. Ringo Brown greedily plunges his hand in the purse, and is bitten. Before he dies, he confesses to Doctor Lassiter and Tom that he had killed Jerry following orders of Jerry Shannon. No more ambushes... Shannon decides to do a frontal assault on Jack's farm, where Tom had found security. The whole gang attacks from everywhere the pair of men who are ready to die then surrender.
Zelda, Shannon's woman, who was already wise to the relationship between Cora and Tom, puts on her nylons and garter belt, and places a small derringer in the garter-belt. Then she enters Cora's room stealthily, locking the door from inside and hiding the key in her bra. Going to the window, Cora sees several men ambushed on roofs, about to murder Tom, and wants to leave, to try and warn him. Zelda pulls out her derringer, and stops her. In the street Tom (Jeff Cameron) and Ringo Brown play a hide-and-seek duel while Cora and Zelda, wearing nightgowns, grapple on their feet, struggling for control of the pistol. They tumble to the floor, where the intense struggle for the derringer continues. Cora sinks her teeth into her foe's wrist, and finally takes control of the struggle, knocking out the saloon's Madam.
Outside, the gun battle rages on, until Tom prevails over his attackers, and Cora interrogates Zelda about Ringo Brown's identity, and purposes...
