As the new season of Legends opens, Martin Odum (Sean Bean) is hunting for his true identity while on the run for a murder he didn't commit. He’s had many undercover personas – legends – but which one is he really? FBI Agent Martin Odum? Wounded Iraq vet John Cameron? Or Russian gangster Dmitry Petrovich? Maybe he’s not really any of those people. His search for answers takes him across Europe, as he discovers his past holds dark and violent secrets he may wish he never uncovered.
