The four teenage werewolves are back in their newest episode, a little older and a little more compromised by their approaching adulthood. This time, they are the target of Jake MacKinnon and Maria Abruzzo's desire for revenge. At an end-of-term party, Jake spikes Noble's drink, turning it into an almost lethal drug cocktail. While Noble is sidelined, events take a disastrous turn. Maria Abruzzo's young sister goes missing, and despite their dislike for Maria, the pack does the right thing by trying to find the girl. As it happens, she has simply snuck off without permission to be with some boys. Everyone, including the police and the pack, is happy she is safe, but are less than pleased by her prank and the trouble she has caused. Maria, embarrassed by her sister and suspicious of the pack, threatens to expose them and whatever it is they are hiding.
