When a female skull is discovered near a railroad track, the Forgotten Network learns Jane Doe's only remaining relative, her comatose sister, could also be in danger.

When a young man falls to his death from atop a skyscraper, the Forgotten Network takes on the near impossible task of identifying him. Their efforts lead them into the world of "Parkour" or free running, where they learn John Doe may have recently returned to America after an extended stay abroad. The case takes an unusual twist when two separate individuals come forward, each claiming the Doe as their own. But which one is really his relative? What brought John Doe back to America? And was it a dangerous Parkour act that got him killed or something more sinister?
