A brazen assassination attempt on an Arizona politician looks unsolvable. The weapon was a drone, and the pilot has carefully covered his tracks. Private investigator Eli Quinn takes the case when his friend, lawman Jack Beachum, suspects the sheriff isn’t investigating rigorously. With three suspects on his list, Quinn pieces the case together with the help of reporter Samantha Marcos, a good friend who is quickly becoming more than that. Quinn also needs back-up from his dog, Solo, the world’s greatest K-9 private eye. As Quinn and his team close in on the suspects, he must use all his fighting skills to stop a threat more sinister than he imagined.
