Dani, a data analyst with an elite security firm, possesses the unnerving ability to read people by the trash they leave behind. Receipts, parking tickets, the detritus of daily life—if you leave it behind, she will figure you out. Her latest case involves high-tech industrial espionage at a corporation with ties to the military. But when a team of assassins sweeps through the firm, stealing all files and killing her coworkers, Dani narrowly escapes. Whoever ordered the strike thinks Dani has vital information and they put a hit man named Booker on her trail. Armed with only her wits and a bag of random investigation materials, Dani must figure out who the enemy really is while playing a high-stakes game of cat and mouse with the cunning hit man who has an agenda of his own.
