And he's missing a shoe. As the investigation begins, Jack surmises he has either stumbled into a conspiracy or there's a serial killer on the loose. The team must mobilize to figure out exactly what is going on. Corruption, kidnapping, and life as they know it all collide as the group comes up against deadly elements within the very organizations they were sworn to protect.

All without being taken out themselves.
