A lovelorn recently out of work pastry chef is down on her luck, and she's recently asked to be the "Maid of Honor" at best friend's wedding. However, due to a series of unfortunate events, she soon finds herself not only competing with the groom's trophy wife over organizing the bridal shower, but she also finds herself having to bluff her way through a comical misadventure that's too hilarious to pass up.

Kate Beckinsale, star of the first two films, returns in her lead role as the vampire warrioress Selene, who escapes imprisonment to find herself in a world where humans have discovered the existence of both Vampire and Lycan clans, and are conducting an all-out war to eradicate both immortal species.

Tribes of vampires and werewolves battle for supremacy among the undead in this follow-up to the horror hit Underworld. Tracing the bloody history of the ongoing war between the Death Dealers, a gang of upper-crust vampires, and the Lycans, a pack of scruffy werewolves, Underworld: Evolution finds beautiful Death Dealer Selene (Kate Beckinsale) and hunky Lycan Michael (Scott Speedman) exploring their own pasts as well as those of their comrades in hope of uncovering the secrets of this centuries-old conflict.
