When a serial killer strikes again in Wolf Lake after over 30 years, Sheriff Donner and Deputy Molly withhold critical information about the case from John Kanin to keep him from finding out about the town's secret. Meanwhile, Tyler brings dinner to Ruby at the secluded cabin where she's being held captive.

During what he thinks is a routine traffic stop, Sheriff Donner is shot three times and hangs on the brink of death as Sophia and Sherman try to convince him that he must become a wolf in order to save himself. In an effort to protect John, Ruby reluctantly marries Tyler.
