Her feelings are complicated by a chance meeting with a good looking cowboy, who Fate keeps throwing in her path.
The only one who seems to understand is her twin brother Sherman, but he will soon return to his home in Toronto, leaving her to deal alone with family expectations, and her own floundering faith.
