Season 4 of the "Buffy the Vampire Slayer" spinoff and the second to last season of this detective comedy cum soap opera, featuring Buffy's ex-boyfriend as the title role. David Borneanaz plays a brooding vampire beset with guilt who has come to L.A. to atone for two and a half centuries spent killing innocents. With a few close and good-looking friends he opens up Angel Investigations and becomes a vigilante determined to fight the forces of evil which run rampant in the city streets. Season 4 opens with Angel being held captive at the bottom of the ocean by a secretly mutinous Connor, while Cordelia has been called to a higher plane by the Powers That Be. After everyone has been reunited within a few episodes, a new villain is unleashed: The Beast, with whom Angel's alter ego, the evil vampire Angelus, used to be in cahoots, has returned from exile to terrorize L.A. Angel is severed from his "good" side by his friends in order to pump his "bad" side for information about this new nemesis, and while Angelus escapes to wreak havoc alongside his old demon friend, uber-villain Jasmine arrives to throw the themes of the show into a cosmic light.
