Set in the 1950s, Adelaine Rudolph plays a rookie agent of the Paranormal Research and Defense Authority (BPRD) who teams up with Hellboy to protect the inhabitants of Appalachia from the terrifying Twisters, who collect souls for demons. Legend has it that Hellboy was discovered as a baby by BPRD founder Professor Trevor "Broom" Bruttenholm and bred to protect humanity from monsters less enlightened than him.
