The Shift That Never Was Department S : Season 2 Episode 5

Something strange has happened at the Bellman-Parsons chemical factory. Although locals claim that they saw the work force arriving as normal, the management report that all of the regular employees reported in as sick, except one, and he is later found murdered. A substitute work force has been using the factory for a plot involving the use of its tankers, a gold robbery and the soon-to-be-opened Northover nuclear power generating station, where Annabelle is held captive by the villains.
