All Cassie wants is to go home to her suburban Atlanta neighborhood, but the time machine that sent her to 1870 vanished.
Drawn to the only familiar structure, a farmhouse built in 1869 and operated as a museum in her time, she meets the owner, Nate, a farmer who was jilted by his fiancée the summer prior.
Nate's cousin passes Cassie off as Nate's fiancée, and his aunt makes plans for the wedding. Nate, having made a promise to God to protect his family and his neighbors, decides to help Cassie find her way home, though he doesn't realize it involves time travel. As they spend time together, they grow close.
Another time traveler has control of the time machine and offers Cassie a choice: follow instructions or remain trapped in the past forever.
Will Cassie deny the feelings she's developed for Nate and return to the present, or will she stay in the past with Nate and trust God for their future?
