During a field trip to Sunnydale Zoo, a gang of students enter the
off-limits hyena enclosure, followed by Xander. The hyenas' spirits
possess the students who begin exhibiting cruel animalistic behaviour
on their return to school.
They pick on the
defenceless; kidnap and devour the school's mascot (a pig named
Herbert); and attack and kill the school Principal. Buffy and Willow
notice the change in Xander's behaviour, and investigate. They
discover that the zookeeper (James Stephens) is behind a plot to
harness the supernatural power of the hyena pack. But Buffy manages
to turn the tables and the pack turn on their leader, the zookeeper.
"It shouldn't be too hard to find a new Principal" muses Buffy
"unless they ask what happened to the last one..."
