Willow meets up with Oz in front of one of the school's trophy cases. He has been
checking out the moving eyes in one of the cheerleading statues, the same one in
which Amy's mother, the witch, is trapped. They discuss their date the previous
night, before Willow spots Buffy and walks outside with her. Willow is worried
because Oz hasn't tried to kiss her yet, although she is happy that he is being so
nice and respectful. Later that night, Xander and Cordelia make out in her car,
which is parked in the woods. Without warning, the hairy arm of a werewolf breaks
through the roof of the car. Cordy throws the car in reverse then brakes, sending
the werewolf tumbling off of the car. They then drive out as fast as they can. The
next morning, Xander tells Giles that they encountered a werewolf. Giles is quite
excited, for he has never personally dealt with a werewolf case before. In gym, the
class is studying self-defense. Xander's latent jealousy of Oz's relationship with
Willow is becoming more and more obvious. Buffy tries to pretend she's a normal
girl, but when Larry grabs her behind during a throw session, Buffy flips him over
her shoulder and onto the mat. Back at the library, Giles has learned that a
werewolf goes on the prowl on the night of the full moon and the two nights
surrounding it, making that a total of three nights in every month.
Later that night, one of Buffy's classmates, Theresa, is walking home alone when
she bumps in Angel, who offers to walk her home. Meanwhile, Buffy and Giles
investigate Lover's Lane in the woods, hoping to find the werewolf and bring it back
alive, for it is still a human twenty-eight days out of the month. Buffy gets trapped
in a net that lifts her to the top of the trees. As she calls for help from Giles, a
poacher named Cain appears with a shotgun. After realizing that his catch is not a
werewolf, he cuts the net down, and Giles helps Buffy out. Cain explains that he
hunts werewolves to make money. He then asks them if they know where else the
teenagers might hang out, since werewolves are attracted to sexual heat. Buffy
feigns ignorance, so Cain leaves and goes off on his own. Buffy and Giles then
drive towards the Bronze, which fits Cain's description perfectly. As they arrive
there, dozens of frightened teens evacuate the Bronze, for the werewolf has
already arrived. Buffy runs inside by herself and pulls a chain out of her backpack.
She tries to tie up the werewolf, but it breaks free of the chain and escapes. While
Buffy and Giles deal with Cain, who is upset that she tried to capture it instead of
kill it, the werewolf wanders down the alleys when it discovers Theresa's body.
There are two bite marks on its neck, and all the blood has been drained from its
body. The werewolf looks up and sees Angel. The two growl at each other, but do
not attack. Angel eventually backs off and disappears.
Early next morning before sunrise, Buffy and Giles hear on the radio that Theresa
was found dead, and her murder may be linked to the werewolf. They now have
only night left before the werewolf goes into remission for the remainder of the
month. As the sun rises, the werewolf slowly transforms back to human form while
it is sleeping. Once all the hair fades away to reveal flesh, we see that the werewolf
is Oz. After waking up and realizing that he is naked in the woods, Oz suspects
that he may be the werewolf. He goes home and calls his aunt. Oz asks her about
his cousin Jordy, who bit him recently. Apparently, his aunt knows that Jordy is a
werewolf, and since he bit Oz, the curse has been passed along. Oz goes to
school that day in a daze, and he is horrified to learn that he may have killed
Theresa the previous night. Xander suspects that Larry may be the werewolf, so he
leaves to question him in the locker room. Willow invites Oz to help her do some
research later that night, but Oz refuses and runs off, leaving Willow upset over his
apparent change of heart. In the locker room, Xander confronts Larry in the locker
room. Xander tells him that he knows the secret that Larry has been hiding, only to
find out that Larry's secret is his homosexuality. Misunderstanding Xander's words,
Larry now believes that Xander is also gay, but assures him that their secret is
safe between them. Feeling relieved and better about himself, Larry thanks Xander
and walks off.
Realizing that the police reports never mentioned anything about Theresa being
mauled, Buffy and Xander visit the funeral home and inspect Theresa's body. Sure
enough, they find two bite marks on her neck, signifying death by vampire. While
Buffy signs the guestbook, Theresa suddenly gets up behind her, only now her
face is that of a vampire. In the middle of their fight, Theresa throws Buffy off guard
by saying that Angel sent her. Luckily, Xander is able to stake her through the
back before she can take advantage of Buffy's disoriented state. After being helped
up, Buffy embraces Xander for a short while, expressing her fear of Angel's
relentlessness. She then realizes her position, gathers herself together, and
leaves, with Xander following behind. Elsewhere, Oz knows that he must not be
able to leave the house that night, so brings out a box of chains and shackles.
Before he can lock himself up, Willow knocks on the door. She is obviously upset
by his decision to stay home and do nothing by himself instead of spending the
time with her. Oz tries to warn her of the danger, but it is too late, for his
transformation has already begun. Willow screams and runs out of the house,
while the werewolf chases her down the block and into the woods. Before he can
attack Willow, a different scent catches the werewolf's nose, so he leaves Willow
alone. She runs off to the library, where Giles is loading up a tranquilizer gun.
Willow tells Giles and Buffy that Oz is the werewolf, so they rush out to the woods.
Buffy kicks the shotgun out of Cain's hand just before he pulls the trigger. After
knockin Cain down, Buffy fights the werewolf, which prevents Giles from getting a
clean shot. Buffy is then knocked into Giles and Willow. As the werewolf charges
them, Willow grabs the tranquilizer gun and shoots him, causing him to stumble
back and collapse. As Cain gets up, Buffy bends his gun with her bare hands, then
orders him to leave.
The next day, Oz tells Willow that he'll be fine, as long as he locks himself up
around the full moon every month. To his surprise, Willow is still interested in
continuing their relationship. As she leaves, Willow kisses Oz for the first time.
