"When the day gives way to night and danger is in sight, it is the one least expected who will make sure you are protected." Shelby Malloy, a recently married twenty-eight-year-old who works for the Law Firm of Cordial, Queria, and Stein befriends two coworkers, Ricky Clay and Paula Queria. Ricky and Paula soon become her closest friends, but are they true friends? While traveling to work one morning by way of the train, Shelby is approached by a small homeless woman named Augusta who asks her for money. Without hesitation, Shelby gives it to her. Unbeknown to Shelby, Augusta continues to watch her and waits for Shelby to exit the train, then follows her off the train until she learns where Shelby lives. Having discovered where Shelby lives, Augusta starts to show up at her apartment continuously. Moved by the woman's plight and wanting to help her, Shelby does the unimaginable, taking a risk that only an exceptional mind could even begin to understand. When Shelby's husband is found dead and her life too is eventually threatened, she starts to realize too late the serious and irreversible impact that making one bad decision can have on a person's life forever.
