When her witness protection cover is blown, Amy Conroy flees across the country. With no money and only her dog for company, she steals rides in the trunks of unsuspecting strangers' cars until a tragic accident lands her in a Key West hospital where she is mistaken for the dead driver. Undergoing reconstructive surgery, Amy becomes almost the mirror image of beautiful Shelly Ralston. Even Matt Jensen, the investigative journalist Shelly was obsessively in love with, believes Amy's the deceased woman. As Amy lives a lie, she begins to fall for Matt herself and soon discovers how deep passions can run. But her idyllic days in Key West are numbered.
