The series is based on the bestseller by American author Jeffrey Deaver, "The Never Game." The main role of Coulter Shaw is played by Justin Hartley. Shaw leads an unusual lifestyle: he constantly travels across the U.S. in an SUV with a trailer and earns a living by searching for missing people and valuables for which a reward has been announced. Each episode is dedicated to a new investigation. Coulter has to search for kidnapped children, save witnesses from murderers, and confront dangerous criminal organizations. Thanks to his observant nature and ability to assess situations, he uncovers clues that law enforcement often overlooks. His survival skills, learned in childhood, also help him. Coulter's father, a professor, suffered from paranoia and feared the authorities, so he took the family far from civilization and taught his children to fend for themselves against dangers. Later, the hero's father died under mysterious circumstances — he was found dead near a cliff in the woods. Coulter is still trying to find out what happened that day and suspects that his older brother may have been involved in the tragedy. This family secret becomes one of the overarching plotlines of the series. “Tracker” combines classic detective work, action, and family drama. Most episodes are self-contained stories; however, viewers gradually learn about the main character's past. The project has gathered a multimillion audience and has become one of the most popular new dramatic shows in the U.S. Justin Hartley has also received nominations for his lead role. The series is suitable for fans of dynamic detective stories where the investigation begins where official searches have already hit a dead end.
