Art Dodge is a painter-turned-gallerist drowning in debt. He gets in over his head when a con job leads to an engagement with a rich divorcee. He gets in deeper when he falls for her sister, and invents a twin brother to be her beau; and deeper still when his fiancée's ex-husband comes looking for revenge.
Hallie Parker and Annie James are identical twins separated at a young age because of their parents' divorce. Unknowingly to their parents, the girls are sent to the same summer camp where they meet, discover the truth about themselves, and then plot with each other to switch places.
