Since nobody anywhere has ever really enjoyed looking at Kate Beckinsale in a skin-tight black catsuit, the actress makes her triumphant return to the Underworld series in the nude. Poor, poor us.

The first trailer for Jan. 20’s Underworld: Awakening was released today, and our hearts are already palpitating for Beckinsale’s return for the fourth installment of the vampire series. (Beckinsale was absent from Underworld: Rise of the Lycans, the prequel released in 2009.) After the opening wardrobe snafu, however, Beckinsale is quickly back in her signature leotard to play butt-kicking, werewolf-slaying vampire Selene. Bummer, right? We know.

This chapter finds Selene, newly escaped from imprisonment, battling to save her species from evil humans working to eradicate both the Vampire and Lycan clans. And as a bonus, the trailer also features a tantalizing first look at a new addition to the series: Selene’s hideous new vampire pal David, played by 26-year-old British actor Theo James.

Watch Selene battles werewolves, pesky humans, and oh-so-inconvenient nudity below:
