When people go missing, conventional search methods often fall short, but Colter Shaw operates by a different set of rules. Justin Hartley stars as this enigmatic lone-wolf survivalist who makes his living as a "reward seeker," tracking down missing persons for the bounties offered by desperate families and law enforcement agencies. Armed with his specialized skills, keen instincts, and an uncanny ability to think like both predator and prey, Shaw traverses the country in his mobile command center, following leads that others have abandoned.

Each case presents a unique puzzle that tests Shaw's resourcefulness and determination. From runaway teenagers to kidnapping victims, from witnesses who have disappeared to individuals who have simply vanished without a trace, no missing person case is too cold or too dangerous for his particular brand of investigation. Fiona Rene appears as Reenie, a lawyer who becomes an important ally in Shaw's unconventional methods of operation.

The series blends procedural elements with character-driven drama, exploring Shaw's mysterious past while delivering tense, high-stakes adventures. As Shaw delves deeper into each case, viewers discover that finding the missing is only half the battle—uncovering the truth behind their disappearances often reveals darker secrets that some would kill to keep buried.
