Josephine Monaghan bears an illegitimate child. She leaves her newborn son under the care of her sister and heads West dressed as a man. She meets Percy, who teaches her about how to survive in the frontier and nurses
a deep suspicion of women. Jo accepts a job herding sheep in the mountains. After returning in the spring, Percy gives Jo a letter from Jo's sister. Percy opened it and knows
he is a
she. Percy promises Jo he will not share her secret if she finances his journey out of the territory. When Jo has enough money saved, she buys her own homestead. One day in town, Jo comes across a mob about to
lynch a Chinese laborer. Jo intervenes, and the "
chinaman", Tinman Wong, goes to live with Jo to help with the homestead. Tinman discovers the truth, and in doing so, reveals he is far more intelligent than he has pretended to be—he, too, has been masquerading for his own safety. The two begin a love affair. The Western Cattle Company wants to buy up all the land in the area, and they kill anyone who does not comply. Jo dons a dress once again in a feeble effort to step back into a more traditionally feminine role. Tinman argues that it will be impossible for her to go back being a society woman, urging her to keep the homestead. Jo is not swayed, and meets with the representative from the cattle company, Henry Grey to tell him she will sell. As Grey prepares the papers, Jo watches his wife who, through the warped glass, is visually reminiscent of Jo when she was a woman of society. Jo changes her mind and refuses to sell. Many years later, Tinman Wong has died. Jo collapses while fetching water, and dies too. The undertaker discovers Little Jo was a woman. The town elders rush back to the undertaker's to inspect. All stand around the preparation table in shock. In town, the people tie Jo's dead body to her horse for a photograph. The final shot is of the newspaper story with before-and-after photographs, and the headline, "Rancher Jo Was a Woman." ==Cast==
