When Aubrey Harrison wrecks her truck on the side of a dark Texas highway, she wakes up in the year 1836, in another woman's life-someone who looks just like her. Struggling to understand her new reality, Aubrey connects with Tapley, a handsome cattleman with a tragic past. As Mexican soldiers begin to fill the small settlement, Aubrey recognizes the first sign of a deadly battle yet to come. A bargain to save her new family's cattle business leads to murder, and Aubrey is forced to take shelter within the walls of the Alamo, even though she knows that's the worst place she could be. The fate of Texas was sealed before the battle ever began, but with it, a new love may now be lost somewhere between the past and the present. An attempt to change fate comes with the high price of Aubrey's future, but she's determined to give history a fight it will never forget.
