Season 3 - Episode 16 "SODUS"

Before the bombs dropped, the Enclave spread its tendrils across
Appalachia, co-opting regional military facilities for their own
use. When President Eckhart assumed control of the Whitespring,
he expanded the faction’s research facilities to further his plan
to end the war with China once and for all…a plan that ended in
ruin.





Stein now leads Valeria and a hand-picked team to one such
facility, only known as Site J, to scour it for weapons and
armor…and more importantly, a potential ally against the PACT and
MODUS.





However, the enemy of my enemy isn’t always a friend…and long
lost secrets can come with a heavy price. 





Meanwhile, Lilith and her own team start their trek to unlock her
father’s secrets underneath the Eastern Regional
Penitentiary…with the PACT close on their heels.





And Trader Red and company try to contact Vault Town, only to
find that they may have gone from the frying pan into the
fire.
