Department S S01 E26 A Small War of Nerves

"Inexplicable... Illogical... No Solution."

LOCATION: Wiltshire, England DATE: April 20th Greg Halliday is fed up with his work as a chemical engineer creating weapons that can obliterate the population of large cities. He leaves his job with a canister of the deadly chemical. The Department is out to find him before others who want the chemicals get to him -- or before Halliday uses the weapon himself.
