Mary DiNunzio's teenage angst comes flooding back when her high school nemesis, Trish Gambone (dubbed "Trash" by Mary) comes seeking her help. It doesn't matter that Mary is now the rainmaker of Rosato & Associates. Trish's mere presence is enough to make Mary feel like she's at the bottom of the food chain. As it turns out, however, Trish's life has taken a horrifying turn. She is terrified of her live-in boyfriend, an abusive South Philly mobster, who just happens to be one of Mary's ex-boyfriends. When Trish vanishes, Mary makes it her personal mission to find her longtime enemy, and works against the clock to save her life.
