Unlicensed P.I. Billie Levine is trying to bank some extra cash, so she picks up hours working as a process server for another investigative firm. Mindless and mostly 9 to 5, Billie is content to simply hand over court documents until during a routine stakeout, she stumbles upon the corpse of an elderly man, an art collector with ties to Nazi Germany.

Compared to Billie, the dead man has it easy. Billie is feeling on edge lately. Maybe it's because her father is insisting his estranged kids come to his wedding in Sedona, or that David is making plans to move out, or that a smug teaching assistant is getting underfoot on her latest case.

Although, it's possible she could use the help when the cops zero in on Billie's boyfriend, Aaron, and his connections to an international art ring. Turns out, Aaron's stint in Israel has left him with more than just a thick scar across his neck. The woman he screwed over wants revenge, and she's determined to leverage Billie's murder case to get it.

With the detectives focused on Aaron, Billie sets her sights on stopping a killer who is tying up loose ends - Billie being one of them.
