Storyline

Investigating the serious poisoning of two navy soldiers by cyanide in the drinking water, the team discovers it's part of a huge stock, enough to kill millions of Californians. That could be the plan of terrorists, but domestic key man Alex Fryman and his adolescent son Dominic are more personally motivated. Written by KGF Vissers
