From shadowy concepts, the Intelligence Support Activity is borne. With no precedent to fall back on - except don't create a mess - the crew of the USS Bellona is forced to navigate the uncertain currents with the Cardassians beating war drums, the Breen militia crippled and the rest of the quadrant on high alert.
On a peaceful, quiet and mostly forgotten colony world bordering the Cardassian Empire, strange things start happening. First come random acts of violence, growing from none to a few dozen. By the time a group of Federation marshals arrive, dozens have turned to hundreds, each caught attacker in a sort of catatonic trance. Then all hell breaks loose when two marshals and some colonists are found dead, and a marshall is identified as the culprit in a similar state. The violence grows to almost epidemic proportions almost as if a disease. Starfleet imposes a quarantine and the Intelligence Support Activity is dispatched. When the ISA arrives, before they can even determine the issue, they must first figuring out how they can even get down to the planet. And they're up against the clock.
