Without a Trace is an American television show set in New York City. The show is about a fictitious full-time FBI missing persons unit. (The real FBI has no such unit; it investigates disappearances periodically as the situation warrants.)

Each episode usually follows the search for one individual under tight time pressure. The stories also focus on the personal lives of the team members, and illustrate how their different experiences give them insight—and sometimes traumatic reactions—to certain cases.
