Season 3 - Episode 17 "Ghosts from the Past"

Dr. Lucius Alistair once fancied himself a god among men. In his
hands, the Forced Evolutionary Virus allowed him to reshape the
human genome into his own twisted vision of perfection.





Before his experiments in Vault 76, before Lilith...Lucius left a
secret legacy deep within the walls of the Eastern Regional
Penitentiary. Long thought lost, Site C could contain a treasure
trove of research and could be the key to unlocking FEV’s full
potential.





Lilith and her team prepare to investigate the old prison, so she
can claim her legacy…but the PACT is hot on their trail, eager to
claim those secrets for themselves. 





In an epic confrontation behind the old prison walls, Lilith will
face off against her fiercest opponent even as Appalachia begins
tearing itself about around them.





Far to the South, Trader Red and her band of survivors find
themselves trapped by the Oni…a desperate message was sent to
Vault Town and help is on the way, but will it arrive on time?





The final tales of Appalachia are being told…and the future is
still uncertain.
