It's Father's Day weekend--a tough time for Charlie D, host of a late-night radio call-in show that offers supportive advice to troubled listeners. For years Charlie has been alienated from his father--a retired politician who was always too busy for his son when Charlie was growing up. The trouble is, his dad has chosen this weekend to attempt to reconcile with his son. Charlie is not keen to forgive. But Charlie's personal issues suddenly seem mundane when an email arrives from a young listener that outlines his very specific plans to kill not just his father but his entire family. The deeply troubled boy could be anywhere, and Charlie has just two hours to discover his identity and stop him from murder.
