Episode 2 of The Underworld series, Selene has chosen her human lover over her vampire family. They are pursued by Markus (last remaining vampire elder). Human lover Michael turns out to be the last blood line descendent of the father of the vampire/werewolf origin, hence containing blood that could be valuable to both. So pursuit, battle, treachery, death... lots of death... The storyline is progressed, but we see (as we usually do with movie franchises) that the movie is not part of a grand plan, but the plan/plot is being made up in service to the movie.
