James Stewart is a Chrono-Cop who has trained his whole life for a mission of incredible importance: He needs to travel back through time to the Old West of 1845 and prevent a tragedy which killed hundreds of people and sparked centuries of mistrust between a group of settlers and a local Comanche tribe. To do this, he’ll make a one-way jump into the body of his nearest living relative at that time: frontier Marshall Edwin Stewart, who made the fatal error that originally sparked the conflict.
However, things don’t go at all according to plan. Instead of being transferred into Edwin’s body as expected, James is instead transferred into the body of a local saloon girl named Rose who has no power to affect the events which James was sent back to change. But it doesn’t change the facts of his mission, saloon girl or not. He’ll have to scramble to find some way to influence Edwin’s fateful decisions while also coming to grips with the fact that he is now a woman—and will be for the rest of his life.
If James can’t complete his objective, hundreds will die, and he might even be among the victims! But as he makes contact with his Edwin and gets to know the rugged and handsome frontier man better, he starts to worry about something more than even that: The strange feelings of love and affection growing in his chest for this dashing western Marshall.
