Instead, she's offered a dream internship with the FBI. She jumps at the chance, and is thrown straight into her first case at house in the Boston suburbs where a family of five have been brutally murdered. As Angela struggles to come to terms with the harsh reality of her new job, a phone is found that could hold the secrets of this mass murder -- if Angela is unable to uncover them.
