In Part II, Marina picks up where the story left off — inside 25 Cromwell Street, where Fred and Rose West had already gotten away with murder. This episode covers the assault on Caroline Owens, the one victim who survived and went to the police — and what happened when the justice system let Fred and Rose walk free. From there, Marina covers the eight young women murdered at Cromwell Street between 1973 and 1979, and the fate of Heather West, the daughter who never made it out.​​​​​​​​​​​​​​​​
