Sam and Dean Winchester head to Wisconsin to investigate a possible werewolf attack on a college campus. Meeting with a hunter named Mick, they agree to team up and investigate the incident. They discover that a young woman named Hayden has been attacked by a werewolf and is in danger of turning.

After rescuing Hayden, the team learns that there is a pack of werewolves on campus and they may be responsible for other recent attacks. With the help of Mick and a new hunter named Claire Novak, the team sets out to take down the pack.

As they investigate, they discover that the pack is led by a female alpha named Tasha who is intent on creating a new, stronger breed of werewolf. Tasha's sister, Sydney, is a reluctant participant in the pack and warns the team of Tasha's dangerous plan.

The team soon learns that Tasha has been experimenting with the werewolf virus, creating a serum that allows her to control her pack members. Dean is captured by the pack and is injected with the serum, becoming a mind-controlled werewolf himself.

With time running out, Sam and Claire race to find a cure for Dean's transformation while Hayden and Mick face off against the pack. After a tense confrontation, the team is able to defeat Tasha and her pack and cure Dean of his werewolf virus.

In the aftermath, Claire considers joining Mick's organization of hunters while Hayden decides to return home and live a normal life. Sam and Dean reflect on the dangers of their jobs and the sacrifices they make to protect others.
