Bloodthirsty vengeance is measured out in buckets, not spoonfuls for this hard-hitting vampire movie sequel.
The story picks up right where the first UNDERWORLD left off, in the midst of a war between Lycans (werewolves) and vampires, with the gorgeous death-dealer, Selene (Kate Beckinsale), on the run with her vamp-wolf hybrid lover, Michael (Scott Speedman). This go-'round, there are flashbacks to three centuries earlier and the separation of two ultra-bad brothers, one vampire and one Lycan. The Lycan gets locked in a hidden tomb/prison and the feud begins.
In the present, the winged vamp brother Marcus (Tony Curran) is determined to find his Lycan sibling and free him, which would wreak unimaginable havoc on the world. Selene's got to stop it, and the result is mayhem, with great gun battles, bashings and hackings, mysterious artifacts, orgies, and sneaking around in the dripping wet crypts and catacombs.
