THRESHOLD Episode 4 "Shock"

An infectee is caught by Baltimore Police whilst trying to steal microchips being brought into the country. They are specific chips being used to make a very advanced and powerful acoustic device, the kind of device that could transmit the signal and infect others. The question is, where was he planning to set it off. The Threshold team have to find some illegal terrorists to trade for their man with another department, but by that time, their man is gone and there's not a lot of time left to stop him.
