The Dawn of Eve goes from from the get-go, when operative Jeanette dies. Leah starts to realise something is happening behind-the-scenes and the girls face a lot of dangerous situations unforeseen by the research crew.
So, how will the Twilight of Adam play out? The guys will likely act more physically aggressive than the girls did, which could cause them to need an earlier rescue. I also think at least one guy will become suspicious about what's going on, like Leah did. An operative or two could also easily die, causing havoc for the researchers.
