 When a student is found savagely mauled in the woods, all suspicions point to Oz, as he s a werewolf during the three-night period of the full moon. However, when Buffy discovers that Angel is back on Earth after apparently enduring hundreds of years of torture in the realm of Hell, and his personality has been reduced to nothing more than a wild animal, she fears that he may be the killer. But unknown to Buffy, Faith or the rest of the gang, the killer is a friend of Scott Hope s, named Pete, who periodically transforms himself into an Incredible Hulk-type rage-beast to kill anyone he suspects that his abused girlfriend, Debbie, confides in with his abuse towards her.
