Texas Rangers James Sandford and Trevor Kent are on a secret mission. A range of robberies have been happening in Fort Smith, Arkansas. They believe it's the notorious, sultry outlaw Isabelle LaRue who's to blame. When they meet the gorgeous saloon singer Belle Samson, they think she's the famous and ruthless outlaw in disguise.

Belle Samson never expected things to get so complicated. Her plan was simple, hang out at Eden's Paradise and pretend to be a saloon singer. But when she meets two handsome, mysterious men at the saloon who don't seem at all the simple cowboys they're pretending to be, she figures she should keep a close eye on them. What she doesn't realize is they planned the same thing.

Soon the spies become the spied and when sexual tension rises to a climactic peak between these three, secrets are revealed that will put them all in danger.
