For the cases no one else can solve, they send in the Special Threat Assessment Team

Supernatural creatures are no longer keeping their existence secret from humans, causing panic around the globe. To investigate, monitor, and—when necessary—take down dangerous supernatural offenders, an international task force was established: The Special Threat Assessment Team.

The only survivor, Jes calls for backup and gets former Navy SEAL and alpha werewolf Jake Huang and his new pack. Convinced that the creature who butchered her teammates was a werewolf, Jes doesn't trust them. But if they're going to uncover the facts and make it back home alive, she'll need Jake's help. And with everything on the line, Jes will have to accept Jake for who he is, or lose the partner she never expected to find...
