For Buffy the Vampire Slayer, birthday’s aren’t all parties and cake — hers tend to involve a life-or-death battle with a big evil. Her seventeenth celebration isn’t an exception. While Buffy’s friends organize a festive gathering in honor of the special day, Spike and Drusilla are planning their own surprise party for the Slayer — with a devastating demon as the grand finale. But a passionate night with Angel changes everything. Suddenly, Buffy must deal with two forms of ultimate evil: the almost indestructible Judge — and the legendary vampire Angelus, who is determined to exact his special brand of revenge on the young woman who showed him true love.
