Joshua Theaker is tasked with finding the killer whose killing methods involve strange weapons. Theaker and local law enforcement find it hard to agree on where the trail goes while local FBI is distracted by child kidnappings. For Theaker, there is a pattern among the victims. But just when Theaker thinks he is getting closer to the killer, he strikes again. And again.
