Molly Crowley was willing to trade in her easy life as a wealthy rancher's daughter for true love.
Molly had a secret: she was in love with Johnny Bravo, a young Mexican working on the Crowley family's ranch, the Circle M. Another Mexican killed her brother, and her father thought all Mexicans can't be trusted. Therefore, she had to keep her love a secret.
Because Molly's father didn't know about Johnny, he was constantly playing cupid. He hired a series of single men to be his ranch foremen in the hope that Molly wanted to marry one of them. His latest hire was a tall, dark-haired cowboy named Cheyenne Bodie. While she gave him a tour of the ranch, Molly let Cheyenne know the real reason he was hired. Cheyenne decided to quit and, as he rode away, Molly begged her father to stop trying to set her up.
That evening, Molly met Johnny out in the barn. The pair had planned to elope and start a new life as homesteaders. But Johnny was reluctant to take Molly away from her easy life on the ranch for the difficult life on a homestead. Molly took his reluctance as rejection.
Their conversation was interrupted when Cheyenne's horse entered the barn without a rider. Johnny left to find out what happened to the cowboy. He brought Cheyenne back to the house, bloodied and beaten by squatters who were feuding with her father. While Molly was nursing Cheyenne back to health, Johnny visited and tried to explain his reasons for not eloping. They kissed and Johnny left. Molly noticed that Cheyenne overheard their conversation. He promised to keep their secret.
The next day, Johnny told Molly that he was leaving the ranch. He can't live a lie anymore. To keep him from leaving, Molly agreed to reveal their relationship to her father. The meeting was a predictable disaster. Crowley was furious when he learned the truth and tried to get his gun but Johnny wrestled him for it. Cheyenne pulled them apart. Their conflict was interrupted by the squatters who killed the local marshal and deposited him on their front porch.
Her father's fight with the squatters flared up. He, Cheyenne and Johnny traveled out to a part of the ranch called Tamarac to confront them. Concerned, Molly followed and found the fight over. The squatters were killed but her father was mortally wounded. Before he died, he gave his blessing to Molly's and Johnny's relationship.
