Bank clerk Stanley Ipkiss is transformed into a manic superhero when he wears a mysterious mask.

When timid bank clerk Stanley Ipkiss discovers a magical mask containing the spirit of the Norse god Loki, his entire life changes. While wearing the mask, Ipkiss becomes a supernatural playboy exuding charm and confidence which allows him to catch the eye of local nightclub singer Tina Carlyle. Unfortunately, under the mask's influence, Ipkiss also robs a bank, which angers junior crime lord Dorian Tyrell, whose goons get blamed for the heist.

Picking up directly from the previous movie, vampire warrior Selene and the half werewolf Michael hunt for clues to reveal the history of their races and the war between them.

Selene, a vampire warrior, is entrenched in a conflict between vampires and werewolves, while falling in love with Michael, a human who is sought by werewolves for unknown reasons.
