Mary and Marshall's first case together in 2003 is revisited after an amorous couple in Baltimore witnesses the brutal killings of the boyfriend's family. Marshall and a reluctant Mary must transport Henry Doer and Claudia Tobin across the country to the safe haven of Albuquerque.
Flash-forward to 2010: Mary and Marshall are rehashing this first case when the couple - now on the road to romantic ruin - jeopardizes their identities when Henry comes to realize that the romance has died.
There's also a new face at WitSec headquarters. The newly appointed U.S. Marshall in town, Allison Pearson, doesn't make a very good first impression with Mary.
Mary's sister, Brandi, is struggling to have her tuition check refunded. And Peter even offers to help her financially, but Brandi has plans of her own.
