Benjamin Harris moves to a small town with his parents called Desertville (The town his father and uncle grew up in). One day, Benjamin Harris visits a diner and encounters a girl named Marley. She claims that Jesus has told her that Benjamin is the one destined to solve the mystery of her father's disappearance. Her father, Joseph Williams, vanished five years before their meeting.

Initially, Benjamin is skeptical-he doesn't believe in such revelations and finds Marley's claim somewhat laughable. Nonetheless, he agrees to help her. Thus begins an unexpected adventure with Marley and her sister, Naomi. Together, they uncover secrets about the T.S.I. (Top Secret Institute), a government facility involved with mysterious jewels and extraterrestrial life.

Yet, the most profound mystery Benjamin Harris will unravel is not just the secrets of the T.S.I. and Marley's father, but one that lies much closer to himself.
