Reese Caldwell has a secret weapon - she talks with her dead twin brother. Together they hunt the scum of the earth, child killers and rapists, and take justice into their own hands. When a world renowned psychic medium unexpectantly enters Reese's life, she is confronted with hiding her secret and compelled to find her brother's long lost murderer.

Hudson Ellis is good at his job. Somehow, he manages not to annoy people when he knocks at their doors and asks them to contribute to the charity he works for - instead, he gets them to sign up for sponsoring programmes and fish whatever spare change they have out of their pockets. Even the infamously tough residents of New York City are falling victim to Hudson's easy-going ways and wide smile; that is, until one woman renders him speechless with sarcastic refusals and slams her door in his face. Perhaps Hudson would be able to forget her - if it wasn't for the fact that she lives on the same floor of the next apartment over, and they both have floor-to-ceiling windows that allow for a rather generous view into each other's flats.
