After a gruelling 18-month work schedule in support of a political campaign in Washington DC, 33 year-old Melody decides to spend some time with her sister's family at their ranch in Montana. She is given an especially warm welcome by her sister Penny, who loses no time in making a list of the local eligible bachelors … a wasted effort, because on her fourth day at the ranch, Melody meets a tall, handsome cowboy called Kendall (Ken) and they soon begin seeing each other.

Not everything goes entirely smoothly though, and it's not long before Ken, who believes in traditional family values, has cause to take the sassy Melody over his knee for a good old fashioned spanking. At first Melody is reluctant to commit to the relationship but it isn't long before she falls head over heels in love with cowboy Ken. She soon discovers that their post-spanking lovemaking more than makes up for a sore bottom!

The relationship flourishes and the couple get engaged. But when Melody returns home to Washington to let go of her apartment and sort out her possessions, she is contacted by Senator Brewster who makes her an attractive job offer that is hard to resist... It's time for Melody to make an important decision. Will she find love and happiness at the end of the rainbow...?
