Bob Winters, a cowboy on the Bar Z ranch, is in love with and loved by Elsie, the daughter of John Marston. the owner of the ranch. When Bob goes to ask Marston for Elsie’s hand, he refuses and a quarrel ensues. Later Marston is seen rescuing a little Indian boy from Dick Thomas, a drunken cowboy, who is beating the little Indian. One night as Bob is eating supper in his cabin a hand appears through the window and takes the knife from his belt. The next morning Marston is found murdered and the knife with which the deed was done is recognized as the one belonging to Bob. A posse is quickly formed and they search for Bob. He is found and charged with the crime, but denies it. The men refuse to listen to his denial and urged on by some of the hot-headed members of the party they decide to lynch Bob. The Indian boy. who has been loitering in the vicinity, goes to the ranch house and tells Elsie that Bob is about to be lynched. She determines to go to the men and plead with them to give Bob a chance to prove his innocence. She arrives at the scene as the rope is about to be pulled, and in an unexpected manner the real murderer is discovered.
