FBI Agent Laurel Evertson's investigation into a scam targeting the elderly takes an unexpected twist when key evidence leads her to Morton Wilmington, a felon she arrested five years ago on her first undercover assignment. That case has haunted her since, and though she's vowed to forget Wilmington - and what she sacrificed to put him away - he is now her best lead.

Houston Police Officer Daniel Hilton fears his grandparents may be the scammer's next targets, and he'll do anything to protect his family - even force interagency cooperation. But he's quickly drawn to Laurel's empathy and zeal and agrees to follow her lead...even if it means teaming up with a felon.

As the unlikely trio uncovers evidence suggesting the scam is more extensive and deadly than they imagined, both Laurel and Daniel find themselves in the crosshairs of a killer. Together they must decide if they can trust Wilmington's claims of redemption or if he's leading them straight into a double cross.
