Biggest mistake ever: Mixing up twins when proposing marriage.

As a newly ordained minister, Lewis is ready to take on his first assignment in Texas... Except he must have a wife. To appease church leadership, Lewis proposes to the girl next door, not realizing the one twin is impersonating the other. Assuming the mistake is destiny, he remains engaged to Catherine.
Devastated at the thought of her twin marrying her long-time crush, Clara agrees to swap places to save Catherine from the marriage she never wanted. Once in Texas, Clara can no longer lie about her identity and must make two wrongs into the right future for her.
Taking a teaching job is Clara's first step, rejecting Lewis's misguided proposal is the second. Somehow, she must convert the preacher to her way of thinking. The only reason to marry is for love.
